Mirrors for Multipass Cells (MPC)
Overview
Nonlinear compression of laser pulses with tens of millijoule energy in a gas-filled 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.
OPTOMAN developed dielectric mirrors optimized specifically for MPC application. OPTOMAN offers flat, concave, and convex broadband mirrors with high reflectivity (R>99.99%), high LIDT (>1 J/cm2 @ 1030 nm, 500 fs) and low and smooth GDD.
