This study reports the construction of a Russian OPCPA-based laser complex. In this system, a 100 TW laser is taken as a front-end system, supplemented with a KD*P crystal with clear aperture of 20times20 cm, as another cascade of parametric amplification. The pump laser comes from one channel of the "Luch" facility with 2 kJ output pulse energy at the wavelength of 1054 nm. In addition,...
LFEX is a high-energy PW laser aiming for an output of 10 kJ/l-10 ps. In this paper the architecture of multi-pass chirped pulse amplifier with 2x2 arrayed structure, newly designed diamond-shape pulse compressor, pulse shaping technique and other technological developments are reported.
Summary form only given. Many laser plasma interaction experiments with ultrashort laser pulses either require or can significantly benefit from the use of a laser pulse with a temporal profile, which has been optimized for the experiment. We will first demonstrate experimentally that self-phase modulation is a serious issue for amplification of shaped pulses in chirped pulse amplification (CPA) systems...
