本文提出了以弱振幅波动分量和强相干分量作为控制场的三能级Λ-type系统中波动诱导双稳的相位控制。随着随机分量的加入，即使来自相应原子跃迁频率的探针场和控制场失谐相等，也可以产生光学双稳性；没有添加物，介质对输入光是透明的。根据随机部分和相干部分之间的相对相位，双稳性出现或消失，阈值强度升高或降低。
We present phase control of the fluctuation-induced bistability in the three-level Λ-type system where a weak, amplitude-fluctuating component and a strong coherent component are used as a control field. With the addition of the stochastic component, optical bistability can be produced even if detunings of the probe and control fields from corresponding atomic transition frequencies are equal; without the addition, the medium is transparent to the input light. Depending on the relative phase between the stochastic and coherent parts, bistability appears or disappears and the threshold intensity is raised or lowered.
