Abstract

Based on gold nanorods as saturable absorbers, diode-end-pumped passively Q-switched Nd:YAG lasers at 1064.3 and 1112 nm were demonstrated. In the 1064.3 nm laser, the maximum average output power was 101 mW. Pulses with 223 ns pulse width and pulse repetition rate of 300 kHz were achieved. In the 1112 nm laser, the maximum average output power of 236 mW was obtained. The shortest pulse width was 504 ns at a pulse repetition rate of 120 kHz.
