Abstract: Fullerene-C60 ,as a kind of new materials used for laser protection,has been studied due to the fact that it is synthesixed and separated successfully in recent years.Optical limiting effect is based on the principles of reverse saturable absorption in C60 and it is one of the significant properties of this material.In this paper,some mechanisms,performances for optical limiting,new studying progresses of C60 are introduced and the application of C60 as an optical limiter material in future is discussed.
