Abstract

A study was made of the dependence of the efficiency of saturation amplification of nanosecond laser pulses in silicate neodymium glass on the width of the spectral distribution of the radiation. It was found experimentally that when the flux density was ~ 1 GW/cm2, an increase in the width of the radiation spectrum from 7 to 10.6 nm increased the gain of an amplifier with a GLS-1 glass active element by 25% and reduced the divergence by 30%.
