Abstract

Cheap and simple low-threshold quasi-cw (1 kHz) barium nitrate based Raman laser excited with the second harmonic radiation of flash-lamp pumped Nd:YAG laser is developed and studied. Created laser system allows one to generate the radiation of five Stokes components at 563.4, 598.7, 638.7, 684.5, and 737.7 nm, simultaneously. Using special resonator mirrors with optimized reflections average powers of the first and second Stokes components higher than 1 W have been reached. It corresponds to Raman conversion efficiency of 30%. The radiation of the Stokes components is frequency doubled in a KDP crystal and the second harmonic radiations at 281.7, 299.4, 319.4, 342.3, and 368.7 nm are obtained with average powers of 10 mW and higher. Narrowing the spectral width of the generated radiation up to about 0.2 cm^-1 in the visible ranage is demonstrated by applying an etalon inside Raman laser resonator. The laser system made can be used for spectroscopic applications and in other field of science and engineering.
