单透射峰Faraday反常色散原子滤光器中检偏器角度的影响
摘要
The effect ofan analyzer angle on the Faraday anomalous dispersion optical filter with single transmission peak operating on the Rb D<sub>2</sub> line 780 nm (5S<sub>1/2</sub>→5P<sub>3/2</sub>) is presented. As comparison, the effects of the analyzer angle on the conventional Faraday anomalous dispersion optical filter with multiple transmission peaks are also studied. When the analyzer angle increases by one degree at room temperature, the peak transmission rate averagely increases by 0.21%. Judged from the relative value, when the analyzer angle is changed from ninety degree to eighty-nine degree, the equivalent transmission rate will be doubled. Moreover, the influences of cell temperature and cell length on the transmission are also introduced.
