当放置在横向磁场中时，内镜 6328-A He-Ne 激光器具有模内频率差。当磁场强度增加直到塞曼频移接近模式间距时，就会产生模式耦合。在一些多模激光器中，这种模式耦合导致崩溃为单模操作，而输出中的总激光功率没有损失。可以利用模内频率差来产生简单的频率稳定系统，其频率变化小于十分之一（10）。包括拍频变化和单模调谐范围的图。
Internal-mirror 6328-A He-Ne lasers have an intramode frequency difference when placed in a transverse magnetic field. When the magnetic field strength is increased until the Zeeman frequency shift approaches the mode spacing, mode coupling is nduced. In some multimode lasers, this mode coupling results in a collapse into single-mode operation with no loss of over-all laser power in the output. The intramode frequency difference can be exploited to produce a simple frequency stabilization system whose frequency variation is less than 1 part in 10(10). Plots of beat frequency variation and single-mode tuning range are included.
