Abstract

A study on Nd:YAG media active laser pumped with millisecond variable pulses in free- running generation and passive Q-switched regime is presented. Different resonator configurations were used: stable plane-plane and spherical-plane resonators usually with reflectivity mirrors or with super-Gaussian variable reflectivity mirrors (VRM) as output couplers and super-Gaussian unstable resonators. In Q-switching operation, laser emission consists in trains of 20 - 50 nanosecond pulses with repetition frequency of 20 - 200 KHz. Peak power pulses of 0.5 - 1 MW were obtained and the laser energy contained in a train of pulses varies from 1 to 8 J depending on the length and energy of the pumping pulse. The beam quality of the Q-switched laser was studied comparatively with free-running laser operation.
