一、前言 He-Ne激光器由三个重要部分组成:一个封装激光物质(He、Ne气体)的放电毛细管,它是产生激光的心脏;激励电源为获得激光提供能源;由反射镜和稳定的机械支架组成的谐振腔,没有它就不能建立激光振荡。一般激光器希望获得TEM_(00)模的最大输出功率,同时考虑输出的稳定性。由于He-Ne激光器是多种工艺的综合结果,在不同条件下需解决的重点问题也各不相同,本文介绍制作40mW的单横模全外腔He-Ne激光器的特色,并侧重于毛细管校直工艺。
I. INTRODUCTION The He-Ne laser consists of three important parts: a discharge capillary that encapsulates a laser (He, Ne gas), which is the heart that generates the laser; an excitation power supply that provides energy for the laser; a mirror that consists of a mirror and a stabilizing mechanism A resonator consisting of a holder, without which laser oscillation can not be established. The general laser hopes to obtain the maximum output power of TEM_ (00) mode, taking into account the stability of the output. As He-Ne lasers are the result of a variety of processes, the key issues to be solved under different conditions are also different. This article describes the characteristics of making 40mW single transverse mode He-Ne lasers and focuses on capillary school Straight process.
