【摘要】 介绍了滤光器的作用以及当前各种应用系统对滤光器的性能要求,原子滤光器与其他传统滤光器的区别,国内外原子滤光器的研究进展.特别地,给出了Faraday反常色散滤光器的重要指标——透过率的普遍计算方法,此计算方法对被动式和主动式Faraday反常色散滤光器都适用,并与实验结果符合得很好.最后对本小组近年来在实验和理论方面的研究成果进行了总结性介绍.其中,Rb-FADOF的实验结果与理论计算吻合得很好,而Cs-ESFAD-OF的新方案在理论上得到了比较好的结果.更多还原

【Abstract】 The function and requirements of optical filter for different systems are introduced,whereby the distinctions of atomic optical filter in comparison to the traditional optical filter are presented and the development of atomic filter is summarized.Furthermore,a general model for calculating the transmittance of Faraday anomalous dispersion optical filter (FADOF) is presented,which is applicable for both passive and active working modes of FADOF.It shows that the theoretical calculation match the experimental results perfectly.Also,we report the progress on the theory and experiment research of passive and active FADOF in our group.更多还原
