Abstract

We have demonstrated an injection-seeded, single-frequency Q-switched Er:YAG laser at the pulse repetition frequency (PRF) of 500 Hz with the ‘double piezoelectric transducers (PZTs) structure’, in a double corner cube retroreflector (DCCR) resonator. With the ‘ramp-hold-fire’ method, the maximum 1.34 mJ pulse energy with a pulse width of 482 ns has been achieved. With the heterodyne beating technique, the full width at the half maximum (FWHM) of the laser spectrum is 1.12 MHz. And the M² factors of the 500 Hz, single-frequency pulsed laser are 1.2, 1.24 along the horizontal and vertical directions.
