title: Cascaded self-Raman lasers based on 382 cm(-1) shift in Nd:GdVO4.
abstract: We report quasi-continuous-wave, cascaded Nd:GdVO(4) self-Raman lasers based on a secondary Raman transition at 382 cm(-1) for which the Raman gain was estimated to be 0.7 cm/GW. Laser output was obtained in the near-infrared at 1108 nm, 1156 nm and 1227 nm. By incorporating intracavity sum-frequency generation (SFG) or second-harmonic generation (SHG), high power output at four discrete visible wavelengths could be selected, specifically 3.4 W at 542 nm, 2.8 W at 554 nm, 1.4 W at 566 nm and 0.8 W at 577 nm, with corresponding diode-to-visible optical conversion efficiencies of 11.7%, 9.7%, 4.8% and 2.7% respectively.
