| 摘 要： | 本文研究了工作在Rb原子D2线（5S1/2→5P3/2）780nm单透射峰的法拉第反常色散原子滤光器（Faraday Anomalous Dispersion Optical Filter,FADOF）中检偏器角度变化对单透射峰的影响,在室温时,发现检偏器角度每增加1°,峰值透射率平均增加0.21%,从相对值来说,从90°-89°时,等效透射率增加一倍.同时测量了检偏器角度变化对传统多透射峰FADOF的影响,以及铷泡温度、长度变化对透射率的影响.

| Abstract: | The effect ofan analyzer angle on the Faraday anomalous dispersion optical filter with single transmission peak operating on the Rb D2 line 780 nm （551/2→5P3/2） 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. |
