GTR-KTP腔内倍频Cr,Nd:YAG自调Q绿光激光器高效稳定输出的研究

Abstract

激光二极管(LaserDiode，LD)泵浦的全固态绿光激光器结合调Q技术和直接泵浦技术，不仅可以缓解泵浦光带来的热效应提高激光器的光学转换效率，而且可以有效缩短激光器的腔长从而产生高峰值功率、重复频率和窄脉宽的绿光脉冲，同时保证激光器结构相对简单易于实现激光器的小型化。为了在LD直接泵浦Cr，Nd:YAG/GTR-KTP腔内倍频自调Q绿光激光器中实现高效稳定绿光输出，本论文从倍频晶体长度、腔长、增益介质的Nd3+离子掺杂浓度等方面进行了相关实验和理论研究。 首先，本论文阐述了LD泵浦的全固态绿光激光器的研究进展，并指出传统方法产生绿光的不足和存在问题。然后论述了非线性光学频率转换相关理论以...

Laser diode (LD) directly pumped solid-state green laser combined with Q-switched technology and direct pumping technology not only alleviate the thermal effect of the solid-state laser, but also can effectively shorten the cavity length of the laser to produce high peak power, repetition rate and narrow pulse width of the green pulse, and the structure is relatively simple and easy to implement t...
