| 摘 要： | 为了获得两束波长不同的可调谐CO2激光脉冲,采用了双光栅与输出镜构成双谐振腔的结构没计。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。

| Abstract: | In order to get a dual-wavelength tunable CO2 laser, a two-resonator laser is developed, which consists of an output coupler and two diffraction gratings. 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. And the output pulse characteristics and tuning range are also analyzed. |
