Abstract :
Nonlinear refractive indices of composite materials doped silver nanoparticles have been measured using the Z-scan technique at the wavelength of 532 nm. Intensity dependent measurements showed the competition of several resonances in composite materials. The mechanisms responsible for nonlinear refraction process are discussed.
