Femtosecond 1030-nm Mirror Thin Film Damage Competition at SPIE Laser Damage

2024.05.08 | Projects

We are proud to announce that Lidaris has been selected once again as the testing facility for the prestigious worldwide SPIE Laser Damage competition, organized by Lawrence Livermore National Laboratory. This double-blind laser damage competition shows currently achievable LIDT values worldwide for multilayer mirrors in the femtosecond regimes. Do not miss Your change to see  where Your optics stands in the crowd.



This year competition evaluates the damage resistance of 1030-nm HR coatings against high and low repetition rate laser pulses using ISO S-on-1 LIDT test protocols. Understanding LIDT dependence on laser frequency is crucial for engineers and laser optics users.

The competition expands knowledge on laser optics limitations across different repetition rates and anonymously reveals the highest achievable LIDTs in the market.


Samples will be tested with femtosecond laser source Pharos PH2-20-SP developed by Light Conversion. Foreseen irradiation conditions are:

  • Wavelength: 1030 nm
  • Pulse duration: ~200 fs
  • Repetition rate: variable: 500Hz and 500kHz
  • Angle of incidence: 0°

The results will be presented at the SPIE LASER DAMAGE symposium in California, October 7-10, 2024.
