Abstract

The experimental results of "Iskra-5" laser operation conversion at the second harmonic. (λ = 657.6 nm) are presented. The experiments were carried out with DKDP crystals of big aperture (size 32 x 33 x 2 cm). The scheme of one channel was upgraded for optimization of second harmonic generation. Maximum conversion efficiency has been achieved for primary laser intensity of 1 - 2 GW/cm². A second harmonic output of 500 J has been obtained at 60% of technical efficiency.
