摘要：
A continuous-wave (CW) laser-diode (LD) pumped passively Q-switched intra-cavity frequency-doubling green laser is reported in this paper. We used 3% at Nd doped YVO4 as gain medium, Cr4+:YAG as a saturable absorber for passively Q-switch and periodically poled LiNbO3 (PPLN) as a frequency doubler. The output energy of the green laser is 1.96 muJ with the pulse-width of 15.6 ns. No green-noise problem exists in the green laser. Some theoretical results on the passive Q-switching and intra-cavity frequency-doubling are also discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.
