AbstractEmploying an acousto-optic modulator (AOM), the Q-switched laser characteristics of a Tm, Y:CaF2 crystal have been investigated. With T = 1%, 2% and 5% output couplers (OCs), output laser performance in both continuous-wave (CW) and Qswitching regimes have been presented and are discussed in details. The AOM Q-switched Tm, Y:CaF2laser can run at high repetition rates ranging from 1 kHz to 10 kHz. Under the modulation frequency of 1 kHz, pulses with the shortest duration of 280 ns and the maximum pulse energy of 0.335 mJ have been delivered, corresponding to a maximum peak power of 1.19 kW. The results indicate that Tm, Y:CaF2crystals can act as a promising candidate of gain medium for pulsed 2 μm laser. © 2017 Optical Society of America.
