Abstract

Applying Cr4+:YAG saturable absorbers, we demonstrate efficient passively Q-switched operation of diode-pumped Nd:YAG lasers with a maximum average output power of more than 800  mW. Pulse durations below 3  ns, energies of 70  µJ, and peak powers of 30  kW are observed with kilohertz repetition rates. Single-frequency operation is accomplished for all output powers by a nonplanar ring geometry.
