全内腔He-Ne激光器开机光强调谐曲线及激光器性能

Intensity tuning curves in boot process and performance of full-inter-cavity He-Ne lasers

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.
