High brightness sources in the 2-3 micron region are essential for many applications including wavelength selective microsurgery, material processing, and gas monitoring . Although there are some rare-earth ions which enable such laser sources like Tm, Ho and Cr, those suitable lasers do not tailor all this spectral range. Solid-state Raman lasers are one of the efficient methods enabling to extend the spectral span of high brightness sources . Over the last five years, this trend was also realized in the 2 micron region, using BaWO4 and YVO4 crystals as Raman gain medium [3,4].
