Laser diode end-pumped continuous-wave BaWO_4intracavity Raman laser and c omposite YVO_4self-Raman laser are reported.By using equivalent G parameter metho d,the cavity mode parameters are calculated with the consideration of the thermal lens in the laser crystal.The laser system is opti mized by designing the cavity construction,pump beam size and choosing the crystal.A high-efficiency continu ous-wave Raman conversion with a BaWO₄Raman crystal in a diode-end-pumped Nd:YVO_4laser has been demonst rated.Since BaWO_4has high Raman gain and good thermal properties,the continuous-wave Raman laser with lo w threshold,high efficiency, good stability and high output power can be realized.The highest output power ob tained at the 1180nm is 3.36W under the diode power of 25.5W,corresponding to a slope efficiency of 15.3% an d a diode-to-Stokes optical conversion efficiency of 13.2%.The Raman threshold is 3.6W of diode power at 808nm.By using composite YVO_4crystal as the laser and Raman medium simultaneously,the diode-end-pump ed continuous-wave self-Raman laser at 1175nm has been demonstrated.The therma l effects can be efficiently improved by using the composite crystal as gain medium.The highest output power obtained at the 1175nm is 3.4W under the diode power of 25.5W,corresponding to a slope efficiency of 14.6% and a diode-to-S tokes optical conversion efficiency of 13.3%.The Raman threshold is as low as 2.21W of diode power at 808nm.
