利用激光边带注入法实现光脉冲的减速和存储
Realization of optical pulse deceleration and storage by using laser sideband injection
摘要
Abstract
Electromagnetic induced transparency,optical pulse deceleration and storage in rubidium atomic vapor are realized based on laser sideband injection method.In order to realize the coherent manipulation of rubidium atoms,the output of master laser is locked on the F =1 → F'=2 transition of D1 line of 87Rb atoms.After modulated by an electro-optic modulator (EOM) with frequency of 6.8 GHz,the negative first frequency sideband generates resonance with the transition frequency of F =2 → F'=2 transition of D1 line.The negative first frequency sideband is injected into the locked slave laser,and the two output beams of the master and slave lasers are two-photon resonant with the two hyperfine energy levels of the ground state of rubidium atom,which can be used to coherently manipulate rubidium atoms.The two output beams of the master and slave lasers can be input into a rubidium vapor cell,as the probe and coupling lights,respectively.Electromagnetic induced transparency,deceleration and storage of optical pulse can be obtained by manipulating the waveform and switch of the two beam.关键词
