Nonlinear compression of laser pulses with tens of millijoule energy in a multipass cell is a promising approach to realize a new generation of high average power femtosecond sources. The whole approach relies on efficient HR mirrors, which enable to have a large number of reflections with low losses.
- High reflection (>99.98%) at a broadband configuration
- Low and spectrally uniform Group Delay Dispersion
- High LIDT (>0.69 J/cm² @ 1030 nm, 180 fs)
