摘要：
A diode-end-pumped passively Q-switched Nd:GGG laser with a double-walled carbon nanotube (DWCNT) saturable absorber is demonstrated for the first time. A maximum output power of 1.03 W and a minimum pulse duration of 24.3 ns with a highest peak power of 121 W were obtained. The pulse repetition rate varied from 122 to 350 kHz as the pump power increased. The experimental results show that DWCNT is an excellent saturable absorber for passive Q-switched lasers.
