Acousto-optic Q-switched broadband tunable single-longitudinal-mode 2 μm laser using a birefringent filter
Single-longitudinal-mode pulse lasers operating at a wavelength of 2 μm are extensively utilized as lidar light sources in gas detection applications. We demonstrated a tunable single-longitudinal-mode acousto-optic Q-switched Tm:YAP laser by a birefringent filter and etalon. With the absorbed pump power of 8.95 W, the laser achieved a pulse duration of 139 ns and a single pulse energy of 1.37 mJ at 1 kHz repetition rate, with an SLM ratio exceeding 99.5 %. The central wavelength was tunable over a wide range from 1887 nm to 2003 nm by adjusting the birefringent filter. Our results provide an effective approach for developing compact mid-infrared solid-state lasers with high power, wide tuning and excellent performance.
