Abstract

The generation characteristics of a barium nitrate Raman laser with pumping by a narrowband tunable nanosecond (tau(p) approximate to 9 ns) Ti:Sapphire laser were studied for the first time. The generation of the first threeStokes components of stimulated Raman scattering (SRS) and their second harmonics was obtained with a spectral linewidth of <0.4 cm(-1) and tuning ranges 930-1250 and 455-625 mn, The efficiencies of energy conversion obtained for the first, second and third SRS components were eta(1s), = 60%, eta(2s), = 49% and eta(3s) = 33%, respectively. On the basis of the investigatedbarium nitrate Raman laser, an all-solid-state laser system was built for various spectroscopic applications, which provides powerful narrowband pulsed radiation tunable in the spectral ranges 345-625 and 690-1250 nn, The applicability of the constructed laser system in Raman spectroscopy was successfully tested by performing a saturation resonance Raman experiment on nickel porphyrin in water solution.
