【摘要】 利用多模压缩态理论,研究了在Kerr介质中自相位调制对多模偶相干态等幂次N次方Y压缩特性的影响,结果发现;1)当压缩阶数N为偶数时,多模Kerr偶相干态在一定的条件下总可随时间变化而周期性地处于等幂次N-Y最小测不准态;2)当压缩阶数N为奇数时,多模Kerr偶相干态在一定的条件下总可随时间变化而周期性地呈现等幂次N次方Y压缩效应.更多还原

【Abstract】 By utilizing multimode squeezing theory, the influences of equal order N -th power Y squeezing property of multimode even coherent state light field by self-phase modulation is studied, and it is found: 1) when the squeezing number N is an even number, Kerr even coherent state can be cyclical on the equal order N-Y minimum uncertainty state with time changing under certain circumstances; 2) when the squeezing number N is an odd number, the multimode Kerr even coherent state cyclically appears equal order N -th power Y squeezing effect with time changing under certain circumstances.更多还原
