Abstract :
Experimental demonstration of low power laser induced optical nonlinearities in copolymers with new pendant azobenzene moieties, is presented. The origin of the huge nonlinearity and the corresponding large Stegeman factor, W, in the continuous wave laser regime, at low power levels, are analyzed.
