Abstract

Three 10-W fiber-coupled diode lasers were used to pump a single Nd:YAG laser crystal. Average output powers exceeding 11 W of continuous-wave 1064 nm, and 3.5 W of 532-nm at 50 kHz pulse repetition frequency were achieved. An L- shaped cavity which compensated for thermal lensing in the laser crystal was utilized. The Nd:YAG rod and an acousto-optical Q-switcher were located in one arm of the cavity while a frequency-doubler was in the other arm. The 532 output beam quality (M²) was 1.5.
