Abstract
A low-cost, compact intracavity deformable mirror (DM) consisting of a mirror unit, a heater unit, a cooler unit and a base unit is proposed to compensate the thermal distortion of a linear resonator passively Q-switched (PQS) laser in this paper. The thermal distortion of the PQS laser is measured using the active deflectometry method. Simulation results indicate that the surface shape of the DM (DMSS) matches well with the measured thermal distortion at the given pumping current. Experiment results verify that the PQS laser with the designed DM could achieve high output power and good beam quality at high pumping currents, as the DM prominently compensates the thermal distortion in the laser.
