Paper Abstract

We present the experimental thermal study of a 88.6 W average power optical parametric chirped pulse amplifier (OPCPA) system operating at 100 kHz, delivering sub-20 fs pulses at a center wavelength of 800 nm. A 15 W pump laser at 1030 nm is used to derive the seed pulses via white-light continuum generation and to pre-amplify the seed pulses to a 1 W level. Further amplification takes place in two high power stages, that are pumped with a frequency doubled Yb:YAG InnoSlab amplifier. The system is a prototype for the future LCLS-II pump-probe laser system.
