摘要

我们利用锶空心阴极灯(HCL)实现了88Sr (5s2) 1so -(55p)1P1跃迁的法拉第反常色散滤光片(FADOF)。在磁场强度为1460 G, HCL放电电流为22 mA时，获得了最大传输率为28.8%的单传输峰。定性地研究了传输对磁场和HCL放电电流的依赖关系。该演示将用于构建法拉第激光器，该激光器将应用于Sr光学时钟。

Faraday anomalous dispersion optical filter at 461nm utilizing a strontium hollow cathode lamp

We realize a Faraday anomalous dispersion optical filter (FADOF) operating on the ⁸⁸Sr (5s²)¹S₀-(5s5p)¹P₁ transition, utilizing a strontium hollow cathode lamp (HCL). At the magnetic field strength of 1460 G and the HCL discharge current of 22 mA, a single transmission peak with a maximum transmission of 28.8% is obtained. The dependence of transmission on magnetic field and HCL discharge current is qualitatively studied. This demonstration will be used to build a Faraday laser, which will be applied in the Sr optical clock.
