| 摘 要： | 讨论了当初始光场处于相干态,原子处于激发态时,非线性J-C模型中光场的振幅平方压缩效应。结果发现,平均光子数n-和脉冲宽度L对压缩深度和压缩时间产生了很大的影响。当脉冲宽度L一定时,压缩深度随着光场平均光子数-n的增加而增大;当平均光子数n-一定时,随着脉冲宽度L的增加,压缩次数和压缩时间区域逐渐增加。

| Abstract: | When the light field was initially in the coherent state and the atom was in the excited state,the effect of amplitude-squared squeezing of light field in the nonliner model containing time was discussed.It was found that average photon numbers and the pulse width had greatly influence on the depth and the time of squeezing.When the pulse width is certain value,the squeezing depth increases with average photon numbers increasing.When the average photon numbers is certain value,the times and time of squeezing gradually increase with the pulse width increasing. |
