Abstract

Spatial-angular and spectral-energy characteristics of eye- safe lasing by SRS in barium nitrate, pumped by 1.32 micrometers Nd:YAG laser radiation in focused beams and resonator are studied. The pump-to-first-Stokes-component energy conversion factor 55% was obtained for lasing in resonator with single-mode pumping. With the multi-mode pumping essential gain in the lased radiation brightness compared with pump (beam clean-up) was received. It was shown that in the focused beams SRS take place in the wave-front replication mode. Thermal lens focal length in crystal was measured.
