摘要
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XeF2初始分子数浓度对XeF激光光谱的影响,结果表明,低XeF2分子数浓度条件不利于XeF(B-X)激光形成,随着XeF2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。
Abstract
The spectrum of XeF laser has been studied using two kinds of resonator mirrors. Two kinds of lasers on B-X and C-A transitions can be obtained under the same experimental condition. The formation time of the XeF(B-X) laser is 800 ns earlier than that of the XeF(C-A) laser. The influence of the original XeF2 concentration on XeF laser spectrum is studied in detail. The experimental results indicate that lower original XeF2 concentration impedes the formation of the XeF(B-X) laser. With the XeF2 concentration increasing,the XeF(B-X) laser presents the characteristic of a series of discrete line spectrum. The spectra of XeF(C-A) laser using two kinds of resonator mirrors are given. The XeF(C-A) laser spectrum is characterized by a continuous broadband spectrum and the absorption lines of atomic Xe can be observed in the spectrum. The narrow band XeF(C-A) laser can be obtained with the appropriate resonator mirrors. The bandwidth of the narrow band XeF(C-A) laser spectrum is 7 nm.
