Paper Abstract

The paper presents results of investigations of three nonlinear absorbers; U2+:CaF2 and Er3+YAG used in generation systems of monopulses of laser radiation of wavelength 1.5 micrometers and V3+:YAG crystals used in systems generating radiation monopulses of wavelength 1.3 micrometers . The transmission changes of the examined absorbers with increase in power density of the passing diagnostic radiation have been determined. There were estimated the following parameters: non-active losses, absorption cross- section, saturation energy, concentration of active centers, relaxation time, and energy losses caused by absorber bleaching. Generation characteristics of erbium-glass laser (1535 nm) with U2+:CaF2 modulator and Nd:YAG laser (1318 nm) with V3+:YAG modulator were investigated.
