Abstract :
In the present work we experimentally study spatial field distribution for SRS beams under picosecond laser pumping of oxide crystals. For an improvement of the low spatial coherence of transient and stationary SRS we demonstrate simple experimental amplification technique which is based on collinear synchronous laser pumping of Raman and LiF crystals with F2 - color centers which possess by broad absorption (850 - 1150nm) and amplification (1000 - 1300nm) bands.
