End-pumped continuous-wave intracavity yellow Raman laser at 590 nm with SrWO4 Raman crystal

We present an end-pumped continuous-wave intracavity yellow Raman laser at 590 urn with a 60 mm long pure crystal SrWO4 and an intra-cavity LiB3O5 frequency doubling crystal. The highest Output power of yellow laser at 590 run was 230 mW and the output power and threshold were found to be correlative with the polarized directions of pure single crystal SrWO4 deeply. Along different directions, the minimum and maximum thresholds of yellow Raman laser at 590 nm were measured to be 2.8 W and 14.3 W with respect to 808 urn LD pump power, respectively.
