Generation of high-power light pulses at wavelengths 1.06 and 0.53 μ and their application in plasma heating. II. Neodymium-glass laser with a second-harmonic converter

A multistage neodymium-glass laser was constructed and its characteristics were determined. Introduction of Fabry–Perot interferometers into the mode-locked laser increased the pulse duration to 1 nsec. The output radiation was converted to the second harmonic in a KDP crystal (the energy efficiency of this conversion was in excess of 50%). The output emergy at the second-harmonic wavelength 0.53 μ was 10 J.
