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

Continuous-wave operation at 588 nm 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 nm 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.
