Paper Abstract

We report the scaling considerations, design details, and experimental results for an efficient, high-power, diode-pumped laser. This Nd:YAG laser produces a cw output power of 60 W in a near-diffraction-limited beam (i.e., M2 < 1.3). In multimode operation, the laser produces an output power of 92 W. The optical-to-optical efficiency is 26% for TEM00 operation and 44% for multimode operation (based on the diode output power). The near- diffraction-limited average power in Q-switched operation is 40 W at a repetition rate 10 kHz. Polarized output powers of 40 W and extinction ratios of 40:1 have also been obtained for cw TEM00 operation.
