摘　　要：主要研究了共振类系统中的三脚架型四能级原子介质被三个光场所驱动,然后将其放入单向环形腔的双稳态行为。通过研究发现驱动场和控制场的频率,合作参数,以及失谐量都能不同程度的影响光学双稳态的产生,还给出了双稳态的阈值宽度以及可调参数的取值范围,为实验上控制和实现光学双稳态提供了理论依据。To study studied the behavior of the tripod type four level atomic medium driven by three light fields in resonant system, then put it to the unidirectional ring cavity. Through the study we found that the driving field and control field frequency, the cooperation parameters, and the detuning can influence the produce of optical bistability in different degree. The bitable threshold width and adjustable parameters are given it can provide a theoretical basis for experimental control and realization of optical bistabilitv.
