摘要
通过优化激光器结构参数和调整反应体系配方, 实现了传统氟化氢(HF)激光输出光谱向长波的转移和波长大于2.87 μm谱线的高效输出。实验和理论结果表明, 随着光轴由11 mm移至15 mm, 2P8谱线所占比重不断减小, 1P10、2P10等谱线所占比重逐渐增加。HF激光输出谱线存在激烈的谱带内竞争和各谱带间竞争, 且在竞争中呈现出一定的级联效应。研究结果拓宽了HF激光实用输出光谱范围, 使某些长波谱线得以高效输出, 对HF激光选线技术研究及应用具有重要的指导意义。
Abstract
The transfer of output spectrum of traditional hydrogen fluoride (HF) laser to long wave and high efficient output of spectral lines, whose wavelength is more than 2.87 μm, is realized by optimizing structure parameters and adjusting reaction system formula. The results of experiment and theory show that the proportion of 2P8 spectral line decreases ceaselessly, and the ratio of spectral lines, such as 1P10, 2P10, increases gradually as the optical axis moving from 11 mm to 15 mm. Moreover, the output spectra of HF laser compete intensely in self and different bands, and cascade effect appears among them. All results extend the utility output spectrum range of HF laser, and make some long wave spectral lines output efficiently, which has an important guiding significance to research and application of the line selected techniques in HF laser.
