Passively Q-Switched Ho,Pr:LiLuF4 Laser at 2.95 μm Using MoSe2

In this letter, we report a diode-end-pumped continuous wave (CW) and passively Q-switched Ho,Pr:LLF laser at 2.95
μ
m. A maximum CW output power of 98 mW was achieved. The highest output power of 58 mW was radiated with a pulse duration of 818.8 ns and a repetition rate of 71.05 kHz. Even shorter pulse duration of 731.5 ns was obtained at a minor output coupler transmission.
