OPTOMAN

Mirrors for Multipass Cells (MPC)

Overview

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.

OPTOMAN developed dielectric mirrors optimized specifically for MPC application. OPTOMAN offers flat, concave, and convex broadband mirrors with high reflectivity (R>99.98%), high LIDT (>0.69 J/cm2 @ 1030 nm, 180 fs) and low and spectrally uniform GDD.

 

Standard MPC mirror can be found at OPTOSHOP
