Optical bistability (OB) and optical multistability (OM) behaviors induced by multiple spontaneously generated coherence (SGC) are investigated theoretically in a tripod four-level atomic scheme. It is found that OB or OM is sensitive to the SGC effects, and the thresholds of OB can be controlled via changing the strength of multiple SGC or the relative phases of the applied fields. In addition, we can switch OB to OM by adjusting the twofold relative phases of the applied fields or vice versa.
在一个三脚架型四能级原子系统中，从理论上研究了由多个自发产生相干（SGC）诱导的光学双稳（OB）和光学多稳（OM）行为。发现OB或OM对SGC效应敏感，并且可以通过改变多个SGC的强度或外加场的相对相位来控制OB的阈值。此外，我们可以通过调整外加场的双重相对相位将OB切换为OM，反之亦然。
