A theoretical model is proposed to analyse the transverse-discharge flow type CO2 lasers. Theoretical expressions are obtained for predicting gain-saturation and output power of flow type gas lasers, these expressions are in agreement with the well-known formulae of non-flowing gas lasers, but the former contains correction terms related to pumping action in the upstream direction of the cavity and the gas flowing effect.

A theoretical model is proposed to analyse the transverse-discharge flow type CO2 lasers. Theoretical expressions are obtained for predicting gain-saturation and output power of flow type gas lasers, these expressions are in agreement with the well-known formulae of non-flowing gas lasers, but the former contains correction terms related to pumping action in the upstream direction of the cavity and the gas flowing effect. Based on the analysis of the variation of intensity in the direction of flow, we derive the limiting values of stauration intensity and other parameters which were attained as the flow speed was being increased. Reliability of the semi-empirical analysis suggested, in literature [1-3] for the flow type laser performance predicted by choosing an average gain-coefficient anl adopting the formulae of non-flowing gas lasers has been proved. The qualitative analysis presented in article [4] is developed into a quantitative calculation. The present model should be used in place of the semi-empirical one, since the formulae deduced are as simple as those for the non-flowing gas lasers. The results computed for both amplifier and oscillator cavities using the present model are in agreement with experimental data [1, 18-21].

本文提出了横流放电CO_2激光器的理论分析模型,导出了稳态发射的基本方程式,得到与熟知的非流动稳态增益饱和及功率理论相同的简单解析关系式。关系式包含了流动效应及光腔上游泵浦效应的修正项。根据强度沿流动方向变化的分析,求得饱和强度等参量在提高流速时的极限值。本文分析为文献[1—3]建议的选择平均增益系数并利用非流动稳态关系计算流动激光器特性的半经验方案提供了理论证明,同时将文献[4]提出的流动激光器的定性分析发展为定量计算。由于本文公式的简单性与非流动情况一样,因而本理论能够取代半经验方案。

Theory and first realization of three types of distributed feedback (DFB) gas lasers

本文论述了三种分布反馈(DFB)式气体激光器的理论及其首次实现的情况,这三种气体激光器是线性DFB激光器、螺旋DFB激光器和与二阶DFB效应相关的切向入射光栅式激光器。这些新型激光器是分别把线性周期金属波导、螺旋型金属波导以及带光栅的楔形金属波导应用到496μm光泵远红外CH_3F激光器上而实现的。螺旋DFB结构在激光研究上是一个新的概念,它引起人们的兴趣不仅在微波技术方面,同样在染料激光器和胆甾醇液晶的研究方面。DFB气体激光器未来研究的一个目标是实现10μm波长的CO_2 DFB激光器,它将具有很优异的特性和应用价值。
