Abstract

We describe a completely passive technique for limiting the power of light beams. The techniques we use are based on optical self-action (self-focusing or defocusing) and non-linear absorption or a combination of both. These processes are passive and thus require no external mechanism to induce limiting other than the light beam itself. We demonstrate picosecond turn on times while 10 secresponse times are possible depending on the material. Specifically we demonstrate optical limiting in CS2 and other organic liquids, and in liquid crystals.
