本实验研究了He-Ne激光两纵模之间的频率分离。给出了一个物理的描述，导致频率分离的变化时，在增益分布的各个位置观察到的模式。频率分离是用快速光电探测器结合计数器作为模式强度比的函数来测量的。用扫描法布里-珀罗干涉仪监测强度比。对于通过增益分布的两个模式的扫描，观察到1.30 kHz的频率分离变化。
In this experiment, the frequency separation between two longitudinal He–Ne laser modes is studied. A description is given of the physics that causes a change in the frequency separation when the modes are observed at various positions in the gain profile. The frequency separation is measured with a fast photodetector in combination with a counter as a function of the mode intensity ratio. The intensity ratio is monitored with a scanning Fabry–Perot interferometer. For a scan of the two modes through the gain profile, a frequency separation change of ∼30 kHz was observed.
