Abstract

A Michelson interferometer has been used to measure the visibility curves for the 6328 A neon emission line in a 90% He-10% Ne gas mixture in order to determine the effect of an optical cavity upon the line shape when the medium exhibits a net gain and yet the system is below lasing threshold. An analytical model for the effect of the cavity is proposed and a computer program set up to fit the model to the data. The cavity gain and finesse are used as variable parameters. The same techniques can be applied to a laser and the number of longitudinal lasing modes can be determined; however, in this case the gain and to some extent the finesse are indeterminate.

摘要

为了确定当介质呈现净增益且系统低于激光阈值时，光学腔对谱线形状的影响，已使用迈克尔逊干涉仪测量了90%氦 - 10%氖气体混合物中6328埃氖发射线的可见度曲线。提出了一个关于腔效应的分析模型，并建立了一个计算机程序，以使该模型与数据拟合。腔增益和精细度用作可变参数。相同的技术可应用于激光器，并可确定纵向激光模式的数量；然而，在这种情况下，增益以及在某种程度上精细度是不确定的。
