LONG-TIME BEHAVIOR OF SQUEEZING OF COHERENT LIGHT IN OFF-RESONANCE JAYNES-CUMMINGS MODEL
非共振Jaynes-Cummings模型中强相干光的长时间挤压行为

The long-time behavior of squeezing of intense coherent light is studied with off-resonance Jaynes-Cummings model. The interaction between field and atom includes both one-photon transition type and two-photon transition type. The analytical formulae for quadrature variances are obtained. In one-photon transition case, small detuning only has small effect on squeezing. For two-photon transition, however, the situation is quite different. No squeezing will occur in resonance case. Only detuning can cause squeezing. Then a series of minimum appear in the suppressed quadrature variance during time evolution. In Urge N limit this se-ries tends to zero.
