Abstract

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.
