Abstract

In this paper, we analyze the role of incoherent pumping field on the control of optical bistability (OB) via the spontaneously generated coherence (SGC) and relative phase between laser fields in a closed three-level ladder-type atomic system. It is shown that in the presence of incoherent pumping field, the influences of the SGC and the relative phase of the OB behavior become more effective. Simultaneously, the threshold intensity and width of the OB reduce significantly when the incoherent pumping rate increases.

非相干泵浦场在封闭三能级阶梯原子系统中的光学双稳态控制中的作用

摘要

在本文中，我们通过封闭的三能级阶梯型原子系统中的自发产生的相干性（SGC）和激光场之间的相对相位，分析了非相干泵浦场在光学双稳态（OB）控制中的作用。结果表明，在存在非相干泵浦场的情况下，SGC的影响和OB行为的相对相位变得更加有效。同时，当非相干抽运速率增加时，OB的阈值强度和宽度会显着降低。
