Efficient cw and passively Q-switched operation with self-stimulated Raman scattering conversion was demonstrated in a compact diode-pumped laser. A cw output power of was obtained with an optical efficiency of 48.2% and a slope efficiency of 78.2% with respect to the incident pump power. Stable Q-switched operation was achieved with a saturable absorber, generating fundamental pulses with a duration of at and Raman pulses with a duration of at . At an incident pump power of , the average output power reached 0.9 and for fundamental and Raman radiation, with slope efficiencies of 32.1% and 14.1%, respectively.
