Abstract

Single-mode-oscillation output power of ~103 mW has been observed in 1.1-at.%-doped Nd:YVO4 pumped with a 500-mW laser diode. Continuous-wave thresholds of ~5.3 mW have been observed with slope efficiencies of greater than 32.4%. The microchip laser can be tuned over 107 GHz, without mode hopping, by heating the laser crystal.
