Transcript of Therapeutic LASER
Overview
• Laser is an Acronym for the Light amplification by the Stimulated emission of Radiation.
• Therapeutic laser is also known as Soft laser, Cold laser, Low intensity laser, class III A B, optic laser
• Laser is a beam of light which is used for various purposes.
HISTORY
• 1962 White & Ridgen• 1964 Flock & Zueng • Applications in different fields• Communication, Industry • Music, Typing• Military, Medical • Dermatology, dentistry, OBG, optahalm,
diagnosis, Physiotherapy

CLASSIFICATION
1. Hot laser• HIL• Surgical Laser• Causes tissue heating• Power > 60mW
2. Cold laser• LIL• Therapeutic Laser• No Tissue heating • Power < 60mW
Types
• 1.Helium Neon Laser : 632.8nm• 2.Ruby Laser: 694.3nm• 3.Gallium Laser : 750nm• 4.Aluminum Laser : 780nm• 5.Arsenide : 810nm• 6.Diodes Laser :820nm• 7.Carbon Dioxide : 10000nm
Types Gas lasers
Helium, neon, argon, carbon dioxide Chemical lasers
Hydrogen fluoride, Solid laser
Ruby laser Diode Laser: like solid but works on
electron
Classification
• Class I/1: Safe, cd players.• Class II/2: 1 mW: blink reflex of eye will
prevent damage. up to 1 mW power, for example laser pointers.
• Class IIIa/3R: 5 mW and staring into such a beam for several seconds is likely to cause (minor) eye damage.
• Class IIIb/3B: immediate severe eye damage upon exposure. Usually lasers up to 500 mW, cd and dvd burners.
• Class IV/4:burn skin, eye and/or skin damage. industrial and scientific lasers are in this class.
PAIN RELIEF
• G.C.T.• Serotonin• Endorphin secretion• Acute & Chronic pain• Pain site, trigger points,• Acupuncture points
Tissue healing
• Phagocytosis, Collagen Synthesis, Contracure• CUMMING’S EXPERIMENT• BIOSTIMULATION THEORY (Biochemical,
Physiological,Proliferative Proliferation offibroblasts,reepithelisation & remodelling)
• PHOTOCHEMICAL THEORY• Chromophores Biostimulation
