| 摘 要： | 本文用热Rb原子进行了光学滤波的研究。将一束激光调谐到Rb原子D2线的F=1→F′=2共振吸收线上,使其泵浦Rb原子,实现原子布居极化(即将Rb原子制备到能级F=2上)。当一束信号光反向穿过该介质时,若信号光频率调谐到原子"吸收窗口"(D1线F=2→F′=2),该介质对信号光大量吸收,信号光透射率仅为0.14%;若信号光频率调谐到原子"透明窗口"(D1线F=1→F′=2),信号光透射率高于47.4%。这种极化的原子介质可以用来做光学滤波器。

| Abstract: | We implement studies on optical filtering with hot Rb medium. A laser with its frequency tuned to the resonance transition F=1→F′=2of Rb medium D2 line pump the atom. So the atom is prepared to energy level F=2. A signal light goes through the medium in the opposite direction to the pump light. If the frequency of signal light is tuned to atomic “absorption window” (D1 line F=2→F′=2), the medium will largely absorb the signal light, and the transmission rate of the signal light is just 0. 14％. But if the frequency is tuned to the “transmission window” (D1 line F=1→F′=2), the transmission rate is about 47. 4％. Therefore, such polarized atoms can be used as the optical filter. |
