摘　　要：采用间接泵浦方法研制了铯原子728 nm激发态原子滤光器。当磁场为4 G的时候,该原子滤光器的透射率为0.304%,带宽为30.9 MHz。与用直接泵浦方法实现的原子滤光器相比,用间接泵浦方法实现的原子滤光器能够达到同样的效果。该原子滤光器不仅能用在激光稳频上,将激光器的频率稳定在原子跃迁线上,还可以用在四能级主动光钟上。该方法还适用于不同波长、不同原子的激发态原子滤光器。We demonstrate a Cs excited-state Faraday anomalous dispersion optical filter(ESFADOF)at 728.00 nm using the indirect pump method by spontaneous emission when the magnetic field is a low magnetic field of 4 G.The filter achieves a peak transmission of 0.304%with a bandwidth of 30.9 MHz.Compared with the traditional direct pump method,the ESFADOF realised by the indirect pump method can achieve the same performance.The ESFADOF realised that using this method can be used in laser frequency stabilisation for some atomic lines and a four-level active optical clock in the future.This method can also be extended to other wavelengths of ESFADOF and widen the application range of the filter.
