Abstract

Summary form only given.We note that the nonlinear optical response for these small cluster compounds is dominated by acoustic/thermal mechanisms at low fluence. At higher fluences, a novel absorptive mechanism contributes to the nonlinear optical response. A consequence is that these materials can act as optical limiting materials with lower thresholds than common suspension limiters such as carbon-black suspensions.
