峰值稳频横向塞曼He—Ne激光器

本文主要介绍一种峰值稳频横向塞曼He-Ne激光器。实验发现激光器输出相互垂直振动的光拍频频率的最大值对应激光器增益轮廓中心。利用调制的方法将激光器输出激光的频率稳定在增益轮廓中心。与国家计量测试研究院的碘吸收稳频标准激光器拍频,频率稳定度为1×10~(-9)。

Peak frequency stabilized transverse zeeman He-Ne laser

A peak frequency stabilized transverse zeeman He-Ne laser is reported in this paper. As a result of experiments we found that the maximum value of the laser's beat frequency of the vertical vibration corresponds to the centre of gain profile of the laser. Based on this specific property, the laser frequency can be stabilized at the centre of gain profile. Comparing with the iodine absorbing stabilized frequency standard laser national standard by the method of beat frequency, we found the frequency stability of this laser is 1×10-9 and it can work continuously over eight hours.
