✦ Synopsis

The nonlinear wave transformation in nanoclusters immersed in a dielectric medium is considered. In nanoscale dimensions the interaction potential of the electron cloud with the ion core has nonlinear corrections which become zero when the cluster radius is increasing. Due to this corrections harmonics of a pump wave may be generated. The effectiveness of the wave transformation as a function of cluster parameters and pump wave intensity is estimated. The phase matching in the case of the third harmonic emission is taken into account. The Mie resonance enhancement of this harmonic is shown to be important. The applications of this effect are discussed.

The third-order nonlinear optical response of collective Na ensembles ('clusters'), bound to mica surfaces, has been studied using cw lasers in a backward-propagating degenerate four-wave-mixing (DFWM) geometry. Largt values of x0) are found, which are independent of cluster size for a range of clus
