All-solid-state 704 mW continuous-wave yellow source based on an intracavity, frequency-doubled crystalline Raman laser

Continuous-wave operation at 588 mn of a diode-pumped Nd: GdVO4 laser with intracavity Raman shifting [in KGd(WO4)(2), KGW] and frequency-doubling (in LiB3O5, LBO) is reported. A maximum cw power at 588 mn of 704 mW was obtained for diode pump powers of 13.7 W. Quasi-cw yellow powers up to 1.57 W at a 50% duty cycle (to reduce thermal load in the laser crystal) indicate that power scaling to over 1 W is feasible. (c) 2007 Optical Society of America.
