摘　　要：本文报道一种高效腔内倍频 Nd:YVO4/ KTP激光器的输出特性以及优质 KTP晶体腔内有效倍频效率和损耗的研究结果。在泵浦功率为 19W时获得了 5 .85 W的连续绿光输出 ,相应的光 -光转换效率为 30 .8%。研究表明 ,优质 KTP晶体腔内有效倍频效率超过 70 % ,最高达到 74.1% ;而其损耗仅为0 .0 0 7cm- 1 。The output characteristics of an effic ient end-pumped Nd:YVO 4/KTP laser,along with the effective iintracavity doubling efficiency and losses of a highly-pure KTP crystal,have been investiga ted.A maximum SHG power of 5.85 W was obtained at the incident pump power of 19 W,leading to an optical conversion efficiency of 30.8 %.It was found that the ef fective intracavity doubling efficiency exceeded 70 % in most of the pump power range,and a maximum value of 74.1 % was reached.It was also found that the losse s of the highly-pure KTP crystal were merely 0.007 cm -1.
