Abstract : This report summarizes the results of our study on two methods for implementing smart material structures which can detect and reject high-power laser radiation over a broad spectrum. Our approaches are based on nonlinear photonic bandgap structures. The first approach is a multilayer system made up of alternating thin films with high and low nonlinearity. The second approach uses nonlinear optical colloids. It was found that the performance of the first approach does not achieve the designed level, because of the lack of suitable nonlinear materials. The second approach exhibits very promising results for rejecting high power laser radiation over a broad wavelength range, while maintains a good transparency at low radiation. Experimental evaluation of the second approach is presented.
