Abstract

Continuous wave (CW) and AO Q-switch operation of a b-cut Tm,Ho:YAP laser with dual wavelengths were reported in this paper. In the temperature of 77 K, the b-cut Tm,Ho:YAP crystal was double endpumped by a 7.21-W fiber-coupled laser diode (LD) at the center wavelength of 792 nm. A 1.17-W Q-switch output power was acquired at pulse repetition frequency (PRF) of 10 kHz, corresponding to an effective optical-optical conversion efficiency of 25.9% and an effective slope efficiency of 31.5%. The energy per pulse of 0.46 mJ in 100 ns was achieved at 2.5 kHz with the peak power of 4.6 kW.
