Continuous-wave Yb:YAP laser with high power diode pumping

High power performance of a continuous-wave Yb:YAP laser was investigated. The laser generated <7 W of output power with 22 W of pump power and slope efficiency of around 70% while maintaining high beam quality. The thermal lensing effect was observed at high pumping power. The combination of high thermal conductivity and broad gain bandwidth make this laser host a suitable candidate for high power CW and ultrashort pulse generation.
