摘要：
An active Q-switched diode-end-pumped Nd:YAG laser is reported with 2.9 W output power on the F-4(3/2) -> I-4(9/2) transitions at a pump power of 24 W. With intracavity frequency doubling using a 20-mm-long LBO, a maximum blue output power of 2.25 W is achieved at a repetition rate of 23 kHz. The conversion efficiency from the corresponding Q-switched fundamental output to blue output is 96%. The peak power of the Q-switched blue pulse is up to 610 W with 160 ns pulse width. The fluctuation of the blue output power is less than 4.0% at the maximum output power. (c) 2006 Elsevier B.V. All rights reserved.
