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,...
This paper presents a 0.5-PW 45-fs laser system based on optical parametric chirped pulse amplification (OPCPA). The 0.56 PW peak power has been achieved experimentally using an upgraded setup. The laser system is very compact, very stable, reliable and easy controllable. It takes a couple of hours for fine alignment and after that the laser generates half-petawatt peak power level pulses each 30...
200TW peak power at 45 fs pulse duration (910 nm central wavelength) has been achieved experimentally using three optical parametrical amplifiers based on KD*P crystals. Energy conversion efficiency of the final amplifier stage was 25%.
A chirp pulse at 910 nm was amplified from 1 nJ to 100 mJ by an optical parametric amplifier Computations show that adding two more parametric amplifiers (100 mm and 300 mm diameter) will result in a multipetawatt power.
