偏振匹配技术使低消光比ＬＮ晶体实现正常调Ｑ西南技术物理研究所第四研究室经努力于１９９３年５月研制成功偏振匹配技术。该技术通过对偏振进行控制与匹配，可使低消化比ＬＮ晶体实现正常调Ｑ并提高Ｑ开关系统的性能。在实验中，我们曾用消光比分别为３０：１，４０：１... Polarization matching technology makes low extinction than the LN crystal to achieve a normal Q-switched Southwest Institute of Technical Physics fourth laboratory by the efforts in May 1993 successfully developed polarization matching technology. The technology through the polarization control and matching, low digestion ratio of LN crystal to achieve a normal Q-switched and improve the performance of Q switching system. In the experiment, we used extinction ratio were 30: 1, 40: 1 ...
