【摘要】 运用半经典量子理论方法建立了光学简并三波混频在两输入场均不为零的情况下的理论模型 ,讨论了在两输入场均不为零时系统的动力学行为以及相应的量子非破坏测量 (QND)特性。研究结果表明 ,该系统的最佳量子非破坏测量工作点与以往的情况不同 ,不是出现在非线性共振点处而是在双稳转变点更多还原

【Abstract】 A quantum theoretical model for the system of degenerate three wave mixing has been established. The dynamical behavior and the features of the optical quantum non demolition (QND) measurement were studied by using nonlinear quantum optics. The results show that the efficient QND measurement can not be well performed at the operation of the nonlinear double resonances (NDR) but the nonlinear transformation of the bistability.更多还原
