为了获得两束波长不同的可调谐CO_2激光脉冲,采用了双光栅与输出镜构成双谐振腔的结构设计.实验中,对影响激光器脉冲输出能量和调谐范围的参量作了具体分析.结果表明,两个谐振腔可以独立振荡输出不同波长的两束激光,二者之间不存在竞争影响,并且均可在大范围内调谐输出:通过对两个光栅做小幅度失谐调整,可以实现两束激光脉冲同步输出.
為瞭穫得兩束波長不同的可調諧CO_2激光脈遲,採用瞭雙光柵與輸齣鏡構成雙諧振腔的結構設計.實驗中,對影響激光器脈遲輸齣能量和調諧範圍的參量作瞭具體分析.結果錶明,兩箇諧振腔可以獨立振盪輸齣不同波長的兩束激光,二者之間不存在競爭影響,併且均可在大範圍內調諧輸齣:通過對兩箇光柵做小幅度失諧調整,可以實現兩束激光脈遲同步輸齣.

In order to get a dual-wavelength tunable CO_2 laser,a two-resonator laser was developed,which consists of an output coupler and two diffraction gratings.The output pulse characteristics and tuning range were also analyzed experimentally.The experimental results indicate that the two resonators can oscillate independently.Two widely tunable laser pulses are generated without spatial competition.The temporal synchronization of the lines is controlled by rotating the gratings within a narrow range for varying their losses.
