介绍了一个适合于本科高年级实验室的激光模式结构实验。对腔模理论进行了综述。本文用光电二极管探测器和频谱分析仪测量了氦氖激光器辐射的模结构。离轴模式可以在扩展的激光束中被视觉检测到，并且它们的存在与光谱分析仪上显示的信号相关联，与理论一致。
Experiments dealing with laser mode structure are presented which are suitable for an upper division undergraduate laboratory. The theory of cavity modes is summarized. The mode structure of the radiation from a helium-neon laser is measured by using a photodiode detector and spectrum analyzer to detect intermode beating. Off-axial modes can be visually detected in the expanded laser beam and their presence correlated with signals displayed on the spectrum analyzer in agreement with the theory.
