利用两种腔镜组合对XeF激光光谱进行了研究。在同一实验条件下,可同时获得B—X和C—A两种跃迁的激光输出,XeF(B—X)激光比XeF(C—A)激光早800 ns形成。详细研究了XeF_2初始分子数浓度对XeF激光光谱的影响,结果表明,低XeF_2分子数浓度条件不利于XeF(B—X)激光形成,随着XeF_2分子数浓度增高,B—X跃迁光谱呈现出多条分立谱线的特征。给出了两种腔镜组合条件下XeF(C—A)激光光谱,XeF(C—A)激光光谱特征是宽带连续谱,在光谱中可观察到Xe原子的吸收线。选用合适的腔镜组合可实现XeF(C—A)激光的窄带输出,带宽约为7 nm。
The XeF laser spectrum was studied by using two endoscopes. Under the same experimental conditions, the laser output of both B-X and C-A transitions can be obtained simultaneously. The XeF (B-X) laser is formed 800 s earlier than the XeF (C-A) laser. The effect of initial XeF 2 concentration on the XeF laser spectrum was studied in detail. The results showed that the low XeF 2 concentration was not conducive to the formation of XeF (B-X) laser. With the increase of XeF 2 concentration, The characteristics of multiple discrete spectral lines. The XeF (C-A) laser spectrum is given under the combination of two endoscopes. The XeF (C-A) laser spectrum is a broadband continuous spectrum, and the absorption line of Xe atoms can be observed in the spectrum. The narrow band output of the XeF (C-A) laser with a bandwidth of approx. 7 nm is made with a suitable combination of endoscopes.
