摘要:理论分析了腔内电磁诱导透明效应(EIT)对腔衰荡光谱(CRDS)的影响,提出了利用V型三能级EIT中的光泵效应提高探测光透过率从而改善CRDS性能的方案。实验中采用铷87原子的D2线构建了V型三能级EIT,在适当的控制光强度下实现了CRDS衰荡时间及其灵敏度的改善,使灵敏度增强至原有灵敏度的1.45倍。
The influence of electromagnetically induced transparency(EIT)on the cavity ringdown spectroscopy(CRDS)is analyzed theoretically.Utilizing the optical pumping effect of EIT in a three-level V-type structure which can increase the transmittance of the EIT medium,we propose a program to improve the CRDS performance.In the experiment,a V-type EIT is constructed with the D2 line of 87 Rb,and the ring-down time and sensitivity of the CRDS system are improved under appropriate light intensity.Finally,the ringdown sensitivity is enhanced to 1.45 times of the original value.
