The diode laser side pumped E-O Q-switch Nd:YAG laser was described that produced energy 0.36-mJ/pulse, 7-ns pulse width, pulse repetition rates 50-Hz, TEM{sub 00} mode. The laser has a zigzag slab geometry, side pumped with a quasi-CW 15W diode bar. The authors used a 1.1% Nd:YAG Brewster-cut seven-bounce thin trapezoidal slab that was 1.2mm thick. Using a cylindrical lens (f = 1.6mm), it made the diode laser couple in the slab. The laser resonator was a plane-concave cavity, radius of mirror curvature was 3m. The cavity length was about 20cm. The plane output mirror transitivity was T = 0.1. They decided to the beam quality M{sup 2} = 1.1. Q-switch laser slope efficiency was 19%.
