Stimulated Raman scattering (SRS) in newly developed BaW04 crystal was investigated. Under 1.9 μm pumping one Stokes component and under 1.56 μm pumping several (up to four) Stokes components were observed. SRS and laser breakdown thresholds were measured. For the first time 2.75 μm and 3.7 μm radiation was obtained using crystalline Raman shifter. A graph is presented. Transmission spectrum of the BaWO4 Raman crystal and Stokes shifted components from the basic 1.56 μm pumping. © 2006 by Astro Ltd.
