title: Near-infrared and orange-red emission from a continuous-wave, second-Stokes self-Raman Nd:GdVO4 laser.
abstract: We report the first cw intracavity crystalline Raman laser operating at the second-Stokes wavelength. Approximately 950 mW emission is obtained at 1308 nm from a Nd:GdVO(4) self-Raman laser, with an overall (diode to 1308 nm) conversion efficiency of 6.8%. By intracavity sum-frequency mixing the first- and second-Stokes lines, 1027 mW emission at 620 nm is demonstrated with an overall (diode-to-visible) conversion efficiency of 4.9%.
