摘      要：Atom–light interface is at the core of quantum metrology and quantum information *** noises during interaction processes are always inevitable and *** this paper,we perform the stimulated Raman scattering(SRS)in a hot Rb 87 vapor cell and demonstrate the reduction of related noises originated from mode mismatch via optimizing the temporal waveform of the input *** using the seed with the optimized mode,the intensity fluctuation of the signal field generated in atom–light interaction is decreased by 4.3 ***,the fluctuation of the intensity difference between the signal and atomic spin wave is reduced by 3.1 *** a temporal mode-cleaning method can be applied to improve the precision of atom interferometry using SRS and should be helpful for quantum information processing based on an atom–light correlated system.
