| 摘 要： | 本文分析半导体材料GaAs对1064nm激光的可饱和吸收特性,在闪光灯抽运的平凹腔和平凸腔Nd:YAG激光器中,插入GaAs样品作为调Q器件,实现了激光器的被动调Q运转,分别获得脉冲宽度32.7ns(平凹腔)和30.9ns(平凸腔)的激光脉冲。实验上研究了平凹腔腔长和输出镜透过率对调Q激光输出性能的影响。当平凹腔腔长增加到125cm时,观察到GaAs对1064nm激光的被动锁模。对上述实验结果给予了合理的理论解释。

| Abstract: | The saturable absorption properties of semi-conduction GaAs for 1064nm laser was researched.In the flashlamp pumped Nd:YAG laser with a plane-concave cavity(PCAC) and a plane-convexity cavity(PCXC),passive Q-switching of GaAs was realized.32.7ns Q-switched laser pulse from the PCAC and 30.9ns Q-switched laser pulse from the PCXC were obtained.The effect of cavity-length and transmission of the output mirror to the laser's properties in the PCAC was studied.When the cavity-length of PCAC increased to 125cm,the passive mode locking of GaAs to 1064nm laser can be observed.The experimental results mentioned above were analyzed theoretically. |
