| 摘 要： | 通过实验比较了Nd:GdYVO4和Nd:YVO4晶体腔内的倍频特性,比较了不同输出透过率和不同泵浦功率时的锁模特性,讨论了影响锁模的主要因素.通过对实验结果的分析得到如下结论:利用连续LD泵浦Nd:YVO4/Cr4 :YAG可以实现调Q锁模激光输出.当腔长较短时,只能实现调Q激光输出,当腔长增加,腔内功率密度增加时,实现了调Q锁模激光输出.

| Abstract: | The intra-cavity frequency-doubled characteristics of Nd:GdYVO4 and Nd:YVO4 and mode-locking behavior at different transmission or at different pump power have been compared,and the primary factor for the influence of mode-locking have been discussed.The results showed that Nd:YVO4/Cr4 :YAG pumped CW LD can realize the Q-switched mode-locking laser output;when the cavity having shorter long can only realize the Q-switched laser output,while the cavity internal power density increased with the cavity long increasing can realized the Q-switched mode-locking laser output. |
