Abstract:

The influence of gamma irradiation on the nonlinear optical properties of Congo dye films prepared by casting method has been reported. The single beam Z-scan technique was used to determine the nonlinear optical properties of the Congo dye doped polymer film. The experiments were performed using cw SDL laser with a wavelength of 532 nm. This material exhibits a negative optical nonlinearity. Optical limiting characteristics of the polymer film were studied. The result reveals that Congo dye doped polymer film can be a promising material for optical limiting applications.
