论文摘要
我们已经研究了通过连续波激光辐射在谐振激发下原子吸收信号的时间行为。对〜1 ns时间分辨率的85RB的D2线进行的测量表明，透射信号的不规则振荡行为对于高激光功率而言非常明显，并且当激光调节异位时消失。传输信号快速傅立叶变换分析的应用揭示了功率依赖性频率峰，这被证明与Rabi频率相关。讨论了观察到的结果与由激光场的相位波动引起的相到振幅噪声转换的可能联系。
We have studied the temporal behavior of the atomic absorption signal under resonant excitation with a continuous-wave laser radiation. Measurements done for D2 line of 85Rb with ~ 1 ns temporal resolution have shown irregular oscillatory behavior of the transmission signal, which becomes well pronounced for high laser power, and disappears when the laser is tuned off-resonance. Application of the fast Fourier transform analysis of the transmission signal reveals power-dependent frequency peaks, which are shown to be associated with Rabi frequency. Possible linkage of the observed results with the phase-to-amplitude noise conversion caused by the the phase fluctuations of laser field is discussed.
