Continuous-wave self-Raman and intracavity doubled laser operation in Nd:GdVO4 at 586.5 nm

We have demonstrated diode-pumped continuous-wave self-Raman operation in Nd:GdVO₄ with output at 1173 nm and intracavity doubled output at 586 nm. We have generated up to 2 W at 1173 nm and 678 mW at 586 nm, limited by thermal lensing in the gain medium. Operating at 50% duty cycle allowed generation of 1.85 W of quasi-CW power at 586 nm. It is expected that by managing the thermal loading and collecting all the generated yellow emission, CW yellow output powers of greater than 3 W will be obtained.
