本文介绍了一种稳定内腔式He-Ne激光器功率包线的综合控制系统。它特别设计用于发射552，505或490 THz（543，594，612 nm）的激光器。其目标是将日常操作的便利性与良好的日常可重置性和一天中最小的频率漂移结合起来，联合收割机。激光器被观察到发射在多达四个模式同时和他们的调谐行为是高度灵敏度。它们还倾向于在具有正交线性偏振平面的模式之间翻转。使用永磁体和通过热膨胀的主动长度控制，可以可靠地控制偏振和模式频率。稳定的单频输出的频率漂移约为每年2×10− 8，功率在150 μW和850 μW之间。
A comprehensive control system has been developed for the stabilization of internalmirror He-Ne lasers to their power envelopes. It is designed particularly for use with lasers emitting at 552, 505, or 490 THz (543, 594, 612 nm). The aim has been to combine convenience in routine operation with good day-to-day resettability and minimal frequency drift during a day. The lasers are observed to emit in up to four modes simultaneously and their tuning behaviour is highly alignment-sensitive. They also tend to flip between modes having orthogonal linear planes of polarization. Reliable control of polarization and mode frequency are possible using permanent magnets and active length control through thermal expansion. The stabilized single-frequency outputs have frequency drifts of about 2×10−8per year, and powers of between 150 μW and 850 μW.
