| Abstract: | The steady bifurcation and phenomenon of critical slowing down of the absorptive optical bistability equation are investigated by using new methods.The existence of optical bistability is proved.It is shown that steady bifurection diagram is the known S shape curve of bistability.The phenomenon of critical slowing down is analyzed.The time of crtical slowing down is estimated. |

| Keywords: | Bifurcation optical bistability and critycal slowing down |
