Abstract

An ultra-narrow bandwidth potassium Faraday anomalous dispersion optical filter (FADOF) at the D₂ line is studied theoretically and experimentally. The effect of temperature on the characteristics of the potassium Faraday filter is discussed and the transmission versus temperature is given. Our research results show that the transmission of the K-FADOF reaches nearly 90% with a bandwidth of only 1.5 GHz. To meet different requirements, K-FADOF can operate at line-center or in the line-wing by changing the working parameters
