摘要：

A laser diode (LD) side-pumped 2 mu m single-frequency Q-switched Tm:YAG laser was demonstrated. The laser was injection seeded by a CW single frequency Tm:YAG laser with a twisted-mode cavity. The maximum single-frequency pulse energy was 16.3 mJ, with a pulse width of 570 ns and a pulse repetition rate of 10 Hz. The linewidth of the 2 mu m single-frequency Q-switched laser was 0.68 MHz, measured by using the optical heterodyne technique. The M-2 of the laser beam was measured to be 1.09 and 1.03 for x direction and y direction, respectively.
