Abstract

We present a diode-pumped, 2 μm single-frequency Q-switched Tm:YAG laser. The Q-switched laser is injection seeded by a monolithic Tm:YAG nonplanar ring oscillator with the ramp-hold-fire technique. The output energy of the 2 μm single-frequency Q-switched pulse is 2:23 mJ, with a pulse width of 290 ns and a repetition rate of 200 Hz. From the heterodyne beating measurement, the frequency difference between the seed laser and the Q-switched laser is determined to be 37:66 MHz, with a half-width of the symmetric spectrum of about 2 MHz.
