摘要
虽然固体激光器和半导体激光器有很多优势,但在精密测量领域,He-Ne激光器仍然是制造高精度仪器最常用的激光器。在开始的升温过程中,He-Ne激光器经历了一段功率、频率、横向模式等不稳定的时间。文中全面、综合地报导了长期实验中得到的丰富的He-Ne激光器(一般和双折射双频激光器)开机光强调谐曲线,并以此作为判断激光器性能的依据,研究如何从曲线对激光器的参数做出推断。包括推断:激光纵模间隔,激光出光带宽,激光单、双纵模区宽度,子腔效应的程度等。
Solid and semiconductor lasers have many advantages, but in the field of precision measurement, He-Ne lasers are still the most commonly used lasers of manufacturing high precision instruments. At the beginning of the warming process, He-Ne lasers went through a instability time of the power, frequency, horizontal mode. This paper comprehensively and integrated report rich intensity tuning curves of He-Ne lasers (General and birefringence dual frequency lasers) covered long-term experiments. As basis for judgment of laser performance, it is used in studies on how to infer laser parameters from the curve. It infer something include: laser′s longitudinal mode interval, single or two longitudinal mode bandwidth, the degree of etalon or interference effect, etc.
