摘要：
We demonstrate a diode-pumped Nd:YAG ceramic laser with emission at 946 nm that is passively Q-switched by single-crystal Cr4+:YAG saturable absorber. An average output power of 1.7W is measured under 18.4 W of incident power using an output mirror with transmission T=4%. The corresponding optical-to-optical efficiency is 9.2%. The laser runs at a pulse repetition rate of 120 kHz and delivers pulses with energy of 14 mu J and duration of 80 ns, which corresponds to a peak power of 175 W. (C) 2011 Elsevier Ltd.
