我们展示了电磁场诱导透明和量子干涉效应在光学双稳等合作现象中的应用。与通常的电磁场的两个级别计划的结果在一个相当大的阈值强度降低的控制字段串联使用。我们讨论了系统的瞬态响应在平均场的限制，并描述回归到稳态时，扰动远离它的回归指数是依赖于控制字段本身。我们还证明了在二能级系统中控制场诱导多稳态的可能性。\textcopyright{} 1996美国物理学会。
We demonstrate the application of electromagnetic-field-induced transparency and quantum interference effects in the cooperative phenomenon, such as optical bistability. The control field used in tandem with the usual electromagnetic field of the two-level scheme results in a considerable lowering of the threshold intensity. We discuss the transient response of the system in the mean-field limit and describe the regression to the steady state when perturbed away from it; the regression exponent is itself dependent on the control field. We also demonstrate the possibility of control-field-induced multistability in two-level systems. \textcopyright{} 1996 The American Physical Society.
