摘 要: | 在被动锁模激光器中,五甲川、十一甲川等染料在不同溶剂中的锁模现象已有报道,但在对撞脉冲锁模激光器中还未见报道。而研究对撞脉冲锁模中可饱和染料的特性对激光系统的性能来说是重要的。本文仅对CPM中使用的五甲川、十一甲川、BDN染料、溶剂、溶液小信号透过率等参数进行探讨和研究。所用的腔为抗共振环形CPM腔,其前反射镜的曲率半径为3m,对撞脉冲用的反射镜为22.5°,1.06μm全反射介质膜片,总腔长1705mm。染料盒放在环路的中心分界处,以布儒斯特角放置,保证损耗小,无子腔,染料溶液放在染料盒中不流动。

Eesearch of saturable absorber for colliding pulse mode-locked Nd:YAG lasers |
| |
Abstract: | In this paper, the mode-locking of pentamathylidyne dissolved in various solvents were studied and their averagepulse duration was measured. The mode-locked pulse trains using pentamethylidyne, undeeamethylidyne and BDN as the saturable absorbers were observed ona 600 MHz oscilloscope respectively, and their mode-locked quality and stability were compared. |
