Abstract
We present our recent work in the development of VECSEL-pumped Raman lasers: power scaling to near diffraction-limited multi-Watt output; investigation of the evolution of emission spectra; analysis of mode-matching, brightness and efficiency; and up-conversion to the visible. We will present a frequency-doubled CW diamond Raman laser pumped by an InGaAs-based VECSEL with an output power of 1.5W at 614nm, 5.4% diode-to-visible conversion efficiency, M2~1.2 and emission linewidth ~0.1nm. The visible emission is tunable from 604.5-619.5nm, with output power exceeding 1W from 613-618nm. We will also report a diamond Raman laser pumped by an AlGaInP-based VECSEL for tunable emission around 740nm.
