HIGHER POWER SQUEEZING EFFECTS FOR ODD AND EVEN q- COHERENT STATES

研究了奇偶 q 变形相干态中光场的高阶压缩效应 .数值计算结果发现 ,奇偶 q 变形相干态中光场的高阶压缩效应与参数值 q有关 ,当参数q取偏离 1较大的值时 ,q 变形奇偶相干态均可具有奇次方阶压缩效应却无偶次方阶压缩效应 。

The higher power squeezing effects of photon field for odd and even q coherent states have been studied. We find that the squeezing effects are influenced by the values of parameter \%q\%, and the odd and even q \|deformed coherent states can exhibit odd power squeezing effect but no even power squeezing effect when parameter q is taken values departure from 1 greatly, and these squeezing characteristics are different from those of the conventional odd and even coherent states.
