1. Fundamental physics with intense lasers2. Laser acceleration to high energies (100GeV, TeV and beyond): need for large-energy laser (PETAL @ LMJ)3. Collider and Low Luminosity Paradigm4. High-average power lasers (ICAN Project)5. Low-energy new fields: Frontier of large number of coherent photons: Dark Matter and Dark Energy fields ‘Shake the vacuum’ by degenerate 4 (laser) wave mixing 6. Mission of IZEST: kJ [large photon number (=Avogadro number)] laser (PETAL) + high-average power laser (ICAN) toward fundamental physics in the international networking (with many willing labs to cover broad parameters)

21st Century; the Photon CenturyCould basic research be driven
by the massless and chargeless particles; Photons (photonics)?

IZEST’s Missions
• An international endeavor to unify the high Intensity laser and the high energy / fundamental physics communities to draw
“The Roadmap of Ultra High Intensity Laser”
and apply it to “Laser-Based Fundamental Physics”
・ To form an international team of scientists that can foster and facilitate scientific missions of EW/ZW class lasers and high average power lasers (ICAN) comprised from ICFA and ICUIL communities (in collab)

Fiber vs. Bulk lasers
• High Gain fiber amplifiers allow ~ 50% total plug-to-optical output efficiency (reachable).
• Single mode fiber amplifier have reached multi-kW optical power.
• large bandwidth (100fs)
• immune against thermo-optical
problems
• excellent beam quality
• efficient, diode-pumped operation
• high single pass gain
• They can be mass-produced at low
cost. 10€/W today and 10C/W in15
years

Dark Matter / Dark Energy (Quantum Gravity Vacuum)
• Weakly interacting particles like axion or axion-like, U(1) gauge bosons with low mass in the sub-electron volt?
• Nonlinear effect in large electromagnetic fields: light shinning through a wall much more sensitive new technique.• Ultralight ultraweak coupling fields of quantum gravity origin (Dark Energy
candidate) in ~ nano-electron volts?
