Abstract
Experimental research of various conditions for effective conversion of "Iskra-5" iodine laser radiation to the second harmonic (λ = 657.5 nm) were carried out. The influence of intensity, depolarization, divergence of main harmonic, optical quality of big aperture (size 32 x 33 cm) DKDP crystals, which are used for conversion and also angular error of their adjustment, was investigated. It was shown that the most essential factors, decreasing the conversion efficiency under Type II phase-matching condition are depolarization and small-scale noise of main harmonic radiation.
