Abstract

Experimental results of two-photon and three-photon excited luminescence in semiconductors and molecular crystals at room temperature are discussed. Dependence of two-photon luminescent intensity upon intensity of pumping light is analyzed for ZnSe samples. The power index of this nonlinear dependence for 532 nm excitation changes from 2 for 6 MW/cm² to 3,6 for 30 MW/cm² excitation intensity. The estimated optical gain coefficient reveals value up to 40 cm^-1. Two-photon copper laser excitation of investigated molecular crystals and organic materials demonstrate luminescence from impurity and excitonic levels.
