摘　　要：通过数值计算研究了增加光子奇q相干态a+mq |α〉oq和增加光子偶q相干态a+mq |α〉eq的高阶压缩效应 结果表明 :当 q较小时 ,态a+mq |α〉oq 和a+mq |α〉eq 都能呈现出强烈的奇次方阶压缩效应 ,但无偶次方阶压缩效应 ,而且奇次方阶压缩随m的增大而增强 当m =0时a+mq |α〉oq 和a+mq |α〉eq 为光场振幅偶次幂的最小测不准态 ,但当m≠The higher power squeezing effects of the photon added even and odd q coherent states (a +m q|α> e q and a +m q|α> o q) is numerically studied.It is shown that for small q,the state a +m q|α> e q and state a +m q|α> o q can exhibit strong odd power squeezing effect but no even power squeezing effect.As m increases,the odd power squeezing increases.The photon added even and odd q coherent states are the even power minimum uncertainty states for m=0,but they are not for m≠0
