A simple and inexpensive frequency stabilization system of a helium-neon two-mode laser with an internal mirror plasma tube is described. The stabilization depends on the comparison of the light intensities of the two operating longitudinal modes. The corresponding frequencies of the modes are symmetrized about the emission line of neon at the transition 3s(2)-2p(4). Experimental results are given. The relative uncertainty of the frequency stabilization is less than 1 part in 10(7).
描述了一种采用内置镜式等离子体管的氦氖双模激光器的简单且低成本的频率稳定系统。该稳定取决于两个工作纵向模式的光强比较。这些模式的相应频率关于氖在3s(2)-2p(4)跃迁处的发射线对称。给出了实验结果。频率稳定的相对不确定度小于10^7分之一。
