| 摘 要： | 采用求解薛定谔方程和数值计算方法,研究了相干态光场与三型运动三能级原子相互作用过程中的光场压缩效应.数值计算结果表明:在相干态光场与运动三型三能级原子相互作用系统中,平均光子数、原子运动速度和场模结构参数对光场的压缩均具有一定程度的影响.在固定原子运动速度和场模结构参数时,增加平均光子数,可以实现完全压缩的光场.随着平均光子数的增加,压缩曲线的振荡周期没有明显的变化,压缩曲线的振荡幅度明显增大,压缩的稳定性变小;在平均光子数和场模结构参数一定时,原子运动速度对光场压缩的深度以及压缩周期影响程度较大,增大原子运动速度,不但可以实现完全压缩光场,而且压缩的稳定性得到提高.

| Abstract: | By means of solving the Schrodinger equation and numerical calculation,the radiation squeezing effects in the system of the coherent states field interacting with a moving-type three-level atom has been discussed.The numerical result indicates that,in the system of the coherent states field interacting with a moving-type three-level atom radiation field,mean photon number,the speed of motion atom and the field mold structure would have the certain degree of influence on the radiation squeeze.When fixed the ... |
