Temperature characteristics of Faraday anomalous dispersion optical filter at Cs 852 nm transition

Known as a unique optical filter, Faraday anomalous dispersion optical filter has prior advantages to provide high transmission and high background noise rejection with excellent image quality. In this paper, we studied the temperature characteristics of Faraday anomalous dispersion optical filter at Cs 852 nm transition. The transmitted spectrum is carefully measured under different Cs cell temperatures (39°C–57°C) and environment temperatures (23°C–26°C). The results could provide important reference for further research on Faraday laser, lidar remote sensing systems and imaging systems.
