摘要：
We report a diode-end-pumped acousto-optically Q-switched composite YVO4/Nd:YVO4/YVO4 crystal self-Raman yellow-green laser, based on the intracavity sum-frequency generation of the fundamental and first-Stokes fields in LiB3O5 crystal. Maximum average output power at 559 nm is 3.55 W at the incident pump power of 32 W and pulse repetition frequency (PRF) of 30 kHz, with an optical conversion efficiency of 11%. The highest pulse energy and peak power are 129 mu J and 10.5 kW at 20 kHz PRF, respectively. The power stability of yellow-green radiation is better than 2% for 40 min at an average output power around 3 W. (C) 2012 Elsevier Ltd. All rights reserved.
