Paper Abstract

We set up a Nd:YAG slab laser and side-pumped with a 2D diode-laser array. The Nd:YAG slab is designed to oscillate with seven internal reflections per pass, and the entrance angle is adjusted to Brewster's angle to minimize the loss. The laser resonator consists of a 2 m radius-of-curvature concave high reflector and a flat output coupler. The diode- array is pulsed for 200 microsecond(s) ec at power of 300 W, and the pump energy of 48 mJ is coupled into the slab. By using an output coupler with transmission of 15.5%, maximum output energy of 8 mJ is obtained with a slope efficiency of 20.2%.
