| Abstract: | The object of experimental study and numerical simulation is the nonlinear optical response from composites with nanoparticles consisting of a nonlinearly absorbing dielectric core and a metallic shell. It is shown that a small spread in nanoparticle sizes near the plasmon resonance may significantly change the dependence of the nonlinear optical response on the concentration of nanoparticles of each size. |
