Abstract

We report the first cw intracavity crystalline Raman laser operating at the second-Stokes wavelength. Approximately $950\mathrm{mW}$ emission is obtained at $1308\mathrm{nm}$ from a $\mathrm{Nd}\text{:}{\mathrm{GdVO}}_4$ self-Raman laser, with an overall (diode to $1308\mathrm{nm}$) conversion efficiency of 6.8%. By intracavity sum-frequency mixing the first- and second-Stokes lines, $1027\mathrm{mW}$ emission at $620\mathrm{nm}$ is demonstrated with an overall (diode-to-visible) conversion efficiency of 4.9%.
