Abstract

Consideration is given to the formation of conditions and parameters of diffuse and volume discharges, which are widely used for laser generation in VUV, UV, visible and IR spectral ranges in different high-pressure gases and gas mixtures. It was found that spectral parameters of volume and diffuse discharges are similar. The difference between these discharge modes is found to be associated with the conditions of their formation. The diffuse discharges are formed due to runaway electrons, for which one or two electrodes with a small radius of curvature are used. To form volume discharges, it is necessary to carry out preionization of the discharge gap using an additional source, as well as to ensure a uniform electric field between the electrodes.

横向放电泵浦高压气体激光器的扩散和体积放电（综述）

摘要

考虑了扩散和体积放电的条件和参数的形成，这些条件和参数被广泛用于在不同的高压气体和气体混合物中产生VUV，UV，可见光和IR光谱范围的激光。发现体积和扩散放电的光谱参数相似。发现这些放电模式之间的差异与它们的形成条件有关。扩散放电是由于电子失控而形成的，为此使用了一个或两个曲率半径小的电极。为了形成体积放电，必须使用附加的源对放电间隙进行预电离，以及确保电极之间的均匀电场。
