A optimized diode-pumped continuous-wave laser with novel Nd:GdLaNbO4 mixed crystal

A diode-pumped continuous-wave (CW) laser with a novel Nd:GdLaNbO4 mixed crystal at 1065 nm was demonstrated. The influence of various parameters on CW output performance was investigated theoretically and experimentally, including the transmission of output mirror, the resonance length and the focusing radius of pump light. When the resonator length was 40 mm and the focusing radius of pump light was 256 μm, the maximum output power of 3.06 W was obtained with optimum output mirror transmission of 20% at absorbed pump power of 12.24 W. The corresponding slope efficiency was 29.1%.
