uncoated optical Windows/substrates

Description

Various dimensions substrates made from BK7, uVFs, IrFs, caF2, ZnSe,Sapphire,MgF2.

standard substrates are laser grade polished on both surfaces. these substratesareidealforbeamsplitters,windows,partialreflectingmirrors etc.

Laser components require highly polished substrates as well as high performance coatings. scattering, damage of laser light can occur if the substrate is made of inferior material or if it is inadequately polished. For uV, very high power applications and ultrashort pulses we recommend using uVFs substrates. BK7 substrates are economical solution for laser components used in many applications in laboratory as well as in devices and instruments.

altechna provides various dielectric and metallic coatings on optical substrates.

Features

Precision uncoated optical Windows/substrates

Description

Being designed as precision windows/substrates to distinguish by supremesurfacepolishingqualityaswellassurfaceflatnessandparallelism, which makes the windows indispensable article for most precision demanding applications. special polishing technique is used todrivesurfacesmoothnessandflatnessnearlytoperfection.Thisproduct is ideal substrate to produce mirrors/polarizers for high power applications since laser induced damage threshold (LIdt) value is closely related to surface polishing quality. Negligible parallelism error (<5 arcsec) causes minimum misalignment errors, when component is repeatedly inserted and removed, this particular property makes it firstchoiceitemwhenoneneedssubstratesforbeamsplittersandthinfilmpolarizerswithminimalbeamdeviation.

Features

• superior polishing quality (10-5 s-d)

• Negligible parallelism error (<5 arcsec)

• Ideal for low scatter demanding applications

• same polishing quality applies to both surfaces

Powell Lenses

Description

the Powell lens has an advantage over cylindrical lenses because later one produces a poorly illuminated line, limited by the non-uniform gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the light in the central area while increasing the light intensity at the line’s end. the outcome is uniformly illuminated line used in all manner of machine vision applications.

Features

• generates uniform laser line

• Fan angle from 1° up to 90°

• Lineuniformitybetterthan25%totalvariationinlineintensity

• Linestraighnessbetterthan0.1%

• custom made lenses also available

Plano-convex axicons (conical lenses)

Description

Plano-convex axicons are conical lenses which are used for variety of applications. When followed by a conventional spherical lens, axicons can focus laser light to a ring shape with annular focus. this feature can be used in hole drilling, microscopy and medical applications. another interesting feature of axicons is a possibility to transform Gaussianbeamintonon-diffractiveBesselbeaminthenearfield.Bessel beams can be used in atom or molecule guiding applications.

Altechnaofferstwotypesofplano-convexaxicons:regularandprecision. regular axicons will create annularly shaped beam whereas precision axicons will also transform gaussian beam into a Bessel beam.Youcanchooseaccordingly,dependingtoyourspecificapplication.

dispersing Prisms

Description

dispersing prisms have three 60° angles therefore they are also referredtoasequilateralprisms.Itprovidesadvantageoverdiffractiongratingswherehigherordersdiffractioneffectisunwanted.Typicalapplications is wavelength angular separation, where the prism is placed in a beam path to refract the beam twice. common scheme is to use the prism in minimal deviation angle, which is achieved by aligning the wavelength of interest to travel in parallel to the prism base. this ensures, that angles of incident and refracted beams are equal in respect to corresponding surfaces. this alignment provides benefitofmaximumclearapertureandleastoverallreflectionlossforp-polarization.

Description

right angle prisms are used to direct beams at 90° by using the hypotenusefacefortotalinternalreflection(TIR).Theseprismsareoftenpreferabletoaninclinedmirrorinapplicationsinvolvingsevereacoustic or inertial loads, because they are easier to mount, and deform much less than mirrors in response to external mechanical stress. as long as acceptance angle limitations for tIr from the roof faces are not exceeded, the right angle prism can also serve as a retroreflector,reflectingabeamback.

dielectric coatings

Description

Dielectriccoatingsconsistoflayerswithdifferentrefractiveindices.there are four major techniques used for dielectric coating: electron-beam deposition (e-beam), ion-assisted electron-beam (Iad), ion beam sputtering (IBs) and magnetron sputtering. all of these processes are quite similar in their principle. they consist of evaporating some coating material and deposit it on the substrate. Thedifferenceliesinthedepositionenergyandmethod.

Because of low energies involved when using electron-beam deposition,thinfilmcontainsbubblesandmicroporeslikeasponge.Thesewilleventuallyfillwithwater,whichwillchangetherefractiveindex of the coating and thus the properties of the optics. (this is knownas“environmentalshifting”).Thepresenceofwateralsolowersthe damage threshold of the optics: when exposed to an intense light, thewaterwilltendtovaporiseanddislodgeoffbitsofthecoating.Finally, even in the absence of water, inhomogeneities of coating layers decrease the theoretical damage threshold. the positive points aboutthistechnologyisthatitiscosteffective,widespreadandveryversatile.Thecoatingitselfisalsoslightlyflexible,whichmakestheoptics more resistant to mechanical stress.

Ion-assisted electron-beam is an intermediate technique, between ion-beam sputtering and e-beam. so are its results.

Ion beam sputtering involves energies 100 times higher than e-beams.

as a result the molecules of the coating layers form covalent bound when deposited. the resulting coating is free from bubbles or pores, more homogeneous, more durable, has higher damage threshold and is more repeatable and controllable. It also exhibits lower scatteringandabsorptionproperties,andoverallhigherspecifications(more broadband, steeper transitions when needed, better spectral stability…). this is high precision coating, and the surface roughness can be controlled at better than 1 Å rMs (!), that is <λ/5000. of course, this comes at a higher cost (atom-by-atom removal is very slow), and even worse, it is limited in the types of coatings it can handle: most of theUVcoatingsforinstanceinvolvefluorideswhichdissociatewhensputtered. In this case, e-beam is the only option.

Magnetronsputteringisusefulforcreatingverydensefilmcoatings(like Ion beam sputtering) with the price similar to electron- beam deposition.Bycreatingastrongmagneticorelectricalfieldduringthe sputtering process, ions and electrons that are generated in the plasmaareconfinedtoadesignatedareaclosertothesourcetarget.this causes more collisions between ions and neutral gas molecules, which creates even more ions that collide with the target and eject material. this process causes a higher rate of deposition. Magnetron sputteringalsohelpsreduceanydamagetothethinfilmcomparedtoothertypesofsputteringbecausethemagneticfieldhelpstheelectronstravelaspecificroute,withoutbombardingthesubstrate.

Description

Hr laser line mirrors (Hr) provide optimized performance at certain wavelength and certain angle of incidence (aoI). Mirror consists of substrate and multilayer coating stacks which help to achieve highreflectanceatspecificlaserlinewavelengthatanydesignedangle of incidence. Laser line Hr coatings are used for external beam manipulation applications where even slight losses may be intolerable. coatings are provided by electron beam evaporation with/without ion assistance coating technique.

e-beam Hr coatings are the most common dielectric coatings in laser optics market as this technology was leading for few decades, and only in recent years it started facing competition with other technologies.

High energy Non-Polarizing Beamsplitter

Non-polarizing beamsplitting plates exhibit a polarization insensitive performance.

Description

In comparison to non-polarizing beamsplitter cubes, our plate beamsplitters feature outstanding performance. cubes typically causeenergylossatapproximately10%,becauseofabsorptioninhybrid metal/dielectric coatings where typically laser induced damage threshold varies in a range of approximately 0.3 J/cm2. Non-polarizing beamsplitting plates design comprises only dielectric layers, thus damage threshold is much higher and exceeds 6 J/cm2. separation of polarizationsRs–Rptypicallyislowerthan5%.Becauseofthisfeaturebeamsplitters are suitable for use with unpolarized light or light of any other state of polarization. standard items have working band width of several tens of nanometers, which makes it versatile. For example beamsplitters designed at 1025 nm - 1095 nm can be used with Yb:KgW, Yb:Yag, Nd:Yag, Yb:glass, Nd:glass lasers. For usage with femtosecond lasers, altechna has designed beamsplitters at 800 nm and400nm,whichdonotinfluencepulsewidth,ascoatingsareGDDcompensated. Non-standard wavelengths and sizes are available upon request.

right angle Prism Mirror

Description

When precise and rigid mounting of bending mirror is needed, right angle prism mirrors provide more advantage than plate mirrors. Mirrorsaredesignedtoreflectlightthatisexternallyincidenttohypotenuse of the prism. Prism angular tolerance of 90° angle is in range of several arc minutes (or arc seconds for precision type). easy mounting does not require further alignment to bend a light at exact 90° angle, what makes the mirrors ideal for rigid optical systems. Four standard metallic coatings are provided. the most common isaluminumcoating,whichfeaturesafairreflectioninUV,visibleand mid - Ir wavelength ranges. other type of aluminum coating islabeledas“UVenhanced”,whichmeansitisdesignedforUVapplications. Protected silver coating is best suited for application in visiblewavelengthrange,whileprotectedgoldisthemostefficientcoatingovertheentireIRrange.However,formaximumreflectanceand highest LIdt, the best choice is dielectric coated mirrors. altechna provides wide range of standard design dielectric coatings, but custom coatings are also available.

Waveplates (Phase retardation Plates) Brief overview

Waveplates (Phase retardation Plates)

Altechnaofferswiderangeofzeroorder(ZO),loworder(LO)half(λ/2) or quarter (λ/4) waveplates for uV, VIs, NIr and Ir (for any wavelength in 240-9000 nm range).

Waveplates are made from materials which exhibit birefringence. the velocity of the extraordinary and ordinary rays through the birefringent materialvariesinverselywiththeirrefractiveindices.Thisdifferenceinvelocitiesgivesarisetophasedifference.Atanyspecificwavelengththephasedifferenceisgovernedbythicknessofthewaveplate.

Half (λ/2) waveplate. a linearly polarized beam incident on a half wave crystal quartz waveplate emerges as a linearly polarized beam but rotated such that its angle to the optical axis is twice that of the incident beam. therefore, half-waveplates can be used as continuously adjustable polarization rotators. Half-waveplates are used in eletrooptic modulation, as a variable ratio beamsplitter when usedincombinationwithathinfilmpolarizerorpolarizingcube,oringeneral to rotate the plane of polarization.

Quarter (λ/4)waveplate-thin-filmcompensator.Iftheanglebetweentheelectricfieldvectoroftheincidentlinearlypolarizedbeamandtheretarder principal plane of the quarter-waveplate is 45 degrees, the emergent beam is circularly polarized. When a quarter waveplate is doublepassed,i.e.bymirrorreflection,itactsasahalfwaveplateandrotates the plane of polarization to a certain angle. Quarter waveplates are used in creating circular polarization from linear or linear polarization from circular, ellipsometry, optical pumping, suppressing unwantedreflectionandopticalisolation.

Features

• Waveplates for any wavelength in the 240-9000 nm range

• Air-spacedZOwaveplatesforhighenergyapplications

• Waveplates for many wavelengths are available from stock

• custom design waveplate assemblies are available on request

custom space Variant retardersDescription

space variant retarders (sVr) fabrication is based on inscription of self-organized nanogratings inside fused silica glass using a femtosecond laser. rapid prototyping enables adaptation of every element to thespecificneedsofenduser(fastaxisandretardancedistribution,structure clear aperture, substrate shape and thickness) without high additional development costs.

sVrs are spatially variable retardance plates which enables tailored control of spatial polarization also for high power lasers. sVrs embedded in bulk of fused silica glass have high damage threshold which is at least 100 times higher than that of liquid crystal devices.

Spatiallyvariablewaveplateexamples(fromlefttoright)apodizingaperture,Fresnel lens and sinusoidal phase grating (shown in cross polarized light).

airy beam converter in cross polarized light.

orientation of induced nanogratings orientation is always perpendicular to laser beam polarization that is used for writing, thereforeitispossibletofabricatepredefinedfastaxisdistributionpatterns(Figure2).Otherpatterns,suchasFresnellens,“soft”aperture,Dammanngratings,flat-topandAirybeamconverters,sinusoidal phase and fork-shaped gratings can be easily realized using this technology.

sVrs have a very broad range of applications from material processing to spinoptics in plasmonics.

Polarization rotators

Description

Polarization rotator is a good alternative to retardation waveplate when it comes to rotation of polarization at certain angle. Polarization rotation is caused by property, called optical activity, which is natural to quartz crystal and other substances that are enantiomorphous. this property is caused by crystal lattice structure, that lacks mirror symmetry due to helicoidal chains of sio4 units oriented along c-axis in quartz structure. depending on chain rotation direction there is“right”and“left”quartzwhichrotatespolarizationclockwiseorcounter-clockwise respectively. Polarization rotators are c-cut so rotation of polarization occurs independently of component’s rotation around optical axis, thus component is alignment-insensitive and the only requirement is that incident beam must be perpendicular to rotator’saperture.Altechnaoffersrotatorswithfixed45°or90°rotationofpolarizationwithantireflectioncoatingsfordesignwavelength.Forconvenient use all rotators are mounted in black anodized aluminum mount. device is good replacement for waveplate, for usage along with narrow band lasers.

glan taylor Polarizers

Description

glan-taylor polarizer is designed to transmit only extraordinary polarization of the beam, while ordinary polarization beam is deflectedtothehousing.Typicalapplicationofthepolarizeris“cleaning”thepolarizationofalightsource,orattenuationofpolarized light source. glan-type polarizers have few advantages over thinfilmpolarizers.Firstly,extinctionratioofGlan-typepolarizerishigher than tFP by 2-4 orders of magnitude, which allows to have better polarization purity. second advantage is broadband spectral operation range, whereas tFP are designed for narrow laser line operation. standard polarizers are mounted into barrel type mounts which are convenient for most applications.

Nd:YVo4 crystals

Description

Nd:YVo4 is one of the best host crystals for diode pumped solid state lasers.

Neodymium doped yttrium vanadate (Nd:YVo4) is widely used as diode pumped solid state laser material. It has a high laser induced damage threshold, good mechanical and optical properties. Its large stimulated emission cross-section and high absorption of pump radiation make it a suitable crystal for pocket laser pointer.

Yb:KgW and Yb:KYW crystals

Description

Yb3+ doped KY(Wo4)2 (KYW) and Kgd(Wo4)2 (KgW) single crystals are well known laser crystals for diode and laser pumped solid-state laser applications.

Yb:KgW and Yb:KYW crystals are used as a lasing materials to generate ultrashort high power pulses. Yb:KgW can be used as ultrashort pulses amplifiersandthesecrystalsareoneofthebestmaterialsforhighpower thin disk lasers.

the broad spectral emission band of Yb:KYW allows the tuning of the laser radiation over 1020-1060 nm range and the generation of femtosecond pulses shorter than 70 fs, enhanced storage capacity, wide absorption spectrum at 980 nm and high absorption of pump radiationinasmallcrystalregionallowsanefficientuseofdiodelaserpump.

as compared to Yag or glasses used as hosts for Yb3+, KYW and KgdW have the advantage of a larger absorption cross section than Yag, which decreases minimum pump intensity necessary to achieve transparency in the quasi-two-level system of ytterbium.

Yb:Yag crystals

Description

Ytterbium doped Yttrium aluminum garnet (Yb:Yag) crystal is one of the most promising laser-active materials.

It is more suitable for diode-pumping than the traditional Nd-doped systems. It can be pumped at 0.94 µm laser output. compared with the commonly used Nd:Yag crystal, Yb:Yag crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-state lifetime, three to four times lower thermal loading per unit pump power. Yb:Yag crystal is expected to replace Nd:Yag crystal for high power diode-pumped lasers and other potential applications.

V3+:Yag crystals

Description

V3+:Yag is a relatively new material for saturable absorber passive Q-switching in lasers emitting from 1.06 to 1.44 µm, in particular, for 1.3 µm Nd-lasers.

extremely high ground state absorption (gsa) cross section of 7x10-18 cm2 near 1.3 µm and negligible excited state absorption (esa) permits Q-switching of 1.3 and 1.44 µm Nd-lasers without intracavity focusingbothwithflash-lampanddiode-laserpumping.Negligibleexcited-state absorption results in high contrast of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10. Finally, excellent optical, mechanical, and thermal properties of the host crystal give an opportunity to design compact and reliable laser sources with this passive Q-switch crystal.

Nonlinear crystals

Description

Beta Barium Borate BBo is a non-linear optical crystal that combines a number of unique features.

these features of nonlinear BBo crystal include wide transparency andphasematchingranges,largenon-linearcoefficient,highdamagethreshold and excellent optical homogeneity. therefore, BBo provides an attractive solution for various non-linear optical applications like oPo, oPa, oPcPa and other. as a result of large thermal acceptance bandwidth, high damage threshold and small absorption BBo is well suited for frequency conversion of high peak or average power laser radiation. the large spectral transmission range as well as phase matching, especially in uV range, makes BBo perfectly suitable for frequency doubling of dye, argon and copper vapour laser radiation, effectivecascadeharmonicgeneration(Frequencydoublers,triplers,parametricamplifiersandwavemixers)ofwidespreadNd:YAGaswellas of ti:sapphire and alexandrite laser radiation. Both angle tuned type 1 (oo-e) and type 2 (eo-e) phase matching can be obtained increasingthenumberofadvantagesfordifferentapplications.

LBo crystals

Description

Lithium Triborate LBos high damage threshold, wide acceptance angle, good thermal stability and wide transmission range make it ideal for frequency doubling of high power lasers.

It is unique in many aspects, especially its wide transparency range, moderately high non-linear coupling, high damage threshold and good chemical and mechanical properties. Its transmission range is from 0.16 µm to 2.6 µm. LBo allows temperature-controllable non-critical phase-matching operation (NcPM) for 1.0-1.3 µm , type I sHg, and also provides room temperature NcPM for type II sHg at 0.8-1.1 µm. It possesses a relatively large angular acceptance bandwidth, reducing the beam quality requirements for source lasers.

Lasers Bragg range Michelson Mode selector (BraMMs)

Description

the patented BraMMs technology provides new wavelengths previously unattainable by cW single frequency dPss lasers in uV, visible and near Ir. It utilizes the spectrum discriminatory feature of a Michelson interferometer setup within a spectral range preselected by Volume Bragg grating. this suppresses all but one lasing longitudinal modewithinalasercavity,hence–BraggRangeMichelsonModeselector (BraMMs).

Duetosignificantlylowerpowerconsumptionforanyrequiredoutputandtheresultingsimplifiedthermalmanagement,theBRaMMSlasertechnology provides up to 10 times wider range of output power scalability from the smallest footprint.

this technology allows any wavelength within the spectrum range from Ir (around 2000 nm) through deep uV (<200 nm) operating in the cW single Frequency regime.

Motorized attenuator assembling steps

Step 1. Place polarizers into mechanical adapter. Polarizers must face each other with surfaces coated with polarizing coating. Polarizing coating is marked with an arrow, so you have to put the polarizers with thearrowsonthesidesfacingeachother.Thenfixpolarizerswiththeplasticbolts(useall4plasticboltstofixonepolarizer).

NotIce: do not tighten up the bolts too much since it can bend the polarizer and thus distort the laser beam.

Step 2. Put wave plate into attenuator between two mounting rings as shown. Be sure the wave plate is immobilized tightly.

Step 3. attenuator consists of two mechanical parts. You should assemble both mechanical parts together.

Step 4.Usefixingscrewfortighteningbothpartstogether.

Watt Pilot - Motorized attenuator, Broadband Version

Description

Ideal solution for NIr and MId-Ir wavelengths, where a wide operation wavelength range is required. Broadband motorized attenuator version incorporates a rotating λ/2 waveplate and glan Laser type polarizer which separates s-polarized and p-polarized beams. s-polarized beam is eliminated in a beam dump, while p-polarized beam’s instenisty is continuously tuned by rotating the waveplate. Watt Pilot is essential in systems, where stable adjustment of laser power is necessary. despite stand alone device look, the motorized attenuator is very compact and can be easily integrated in custom optical systems.

Features

• Wide operation range in NIr and Mid-Ir spectrum

Fixed ratio Beam expanders

Description

altechna’s beam expanders are assembled using one diverging and one converging lenses, so there is no focal point inside the beam expander, thus it can be used for high powers. For low expansion ratios (1.3 - 20 times) the galilean beam expander is preferred due toitssimplicityandsmallsize.Weofferbeamexpandersmadefromtwo, three, or more spherical lenses made from BK7, Fs, uVFs or other glasses which suit high power applications. Beam expanders for any wavelengths between 266 - 2000 nm are available on request.

Features

• compact size

• High power applications

• Max input beam diameter (1/e2) of 3-5 mm for diffraction-limited performance

• Mounting thread sM1

• custom magnification and design on request

Laser Beam shapers

Description

piShaperproducesacollimatedflat-topbeamoveralargeworkingdistance. these unique tools enable converting a gaussian laser beam intoacollimatedflattop(ortop-hat)beamwithnearly100%efficiency.

ThemainbenefitofusingpiShaperislaserenergysavingwhichisvery important in many laser applications, especially in material processing. gaussian intensity distribution is not an optimal one in manycases.Fromthispointofviewtheevaluationoftheefficiencyofusing laser energy is very important.

Basic principles of operation

• pishapers are telescopic or collimator optical systems that transform gaussian intensity distribution of source laser beamtoaflattopone;

• achromatic design provides this transformation for a certainwavelengthrange;

• galilean design, thus there is no intermediate focusing of a beam.

Laser beam shaping systems for micromachining applications the best choice for manipulation of focused beam is Focal-piShaper_xxx.“Flattop”,“donut”,“InverseGauss”,“Trident”,“Roof”andothershapescanbecreatedinthefocalregionofanydiffractionlimitedlens.

spectacles and goggles type safety glasses

Description

WarNINg: don’t look into the laser beam with your remaining eye, wear safety glasses!

Working with lasers is completely safe as long as adequate eyesight protection is used. otherwise, laser radiation can induce severe and oftenirreversibledamagetoretinaorcornea.Takeadvantageofourprofessional anti-laser spectacles and goggles which are comfortable and absolutely safe (if selected properly).

Selecting appropriate laser eye protection

the choice of the most suitable safety spectacles or goggles must be made in compliance with eN 166, eN 207 and eN 208 standards. use of unsuitable eye-wear is one of the most frequent causes of eye injury. For the correct judgement of optical hazards, it is important to know someofthefundamentalparametersdefinedinthestandardsofeye-protection against laser radiation. Please, consider the following as a guide.

• Laser wavelength. determine all the wavelengths which need to be protected against with the one pair of glasses.

• Output parameters. to calculate the power density (W/m²) of continuous wave lasers check the maximum output power and beam diameter. For pulsed lasers determine the maximum energy, the beam diameter, and the frequency (if applicable) to calculate the energy density (J/m2) or power density.

• Spectral transmittance and optical density. spectral transmittance is the ratio between the power (or energy) transmittedbythefilterandthepowerofincidentradiation.Findthe recommended minimum power (or energy) density value whichtheprotectionfiltermustcomplywithintheEN166,EN207 or eN 208 standards tables - the closest greater value to your calculation. optical density is related to transmission by the equation: d = -log10 t.
