Abstract
An acousto-optic Q switch, a resonant cavity, and a pulse laser device for improving laser device power. The acousto-optic Q switch includes: a transparent optical element configured to form a phase grating that diffracts laser; a piezoelectric transducer arranged at one end of the transparent optical element and configured to convert electrical energy into ultrasonic energy to form the phase grating in the transparent optical element; and an absorber arranged at the other end of the transparent optical element to absorb the ultrasonic energy.
