摘要：
By using a piece of GaAs wafer as the saturable absorber, the performance of the passively Q-switched composite Nd:YVO4 laser with different output couplers has been demonstrated for the first time as far as we know. The largest continuous wave output power of 1.52W is obtained at the incident pump power of 5.31W, giving an optical conversion efficiency of 28.7% and a slope efficiency of 30.2%. The shortest pulse width of 11 ns, the largest single-pulse energy of 2.49 mu J and the highest peak power of 190W are also obtained. (C) 2014 Elsevier GmbH. All rights reserved.
