Paper Abstract

All-solid-state diode-pumped intracavity Raman laser was realized. The laser was based on three-mirror linear cavity with triangular Brewster-angle-cut Nd:YAG slab crystal pumped by 300 W quasi CW diode Q-switched by Cr4+:YAG saturable absorber operated at 1064 nm. The BaWO4 crystal (6×6×33 mm) was used as a Raman converter. After the Raman laser optimization for the first Stokes (1180 nm) the reproducible conversion efficiency was about 40%. The corresponding output energy and pulse duration were 1.46 mJ and 3.5 ns, respectively. The highest Raman laser output energy was reached 2.3 mJ (efficiency 55%). The second and third Stokes with first anti-Stokes lines were also detected at the laser output.
