Specific features have been revealed of nonlinear optical processes occurring when the total energy of two photons of a mode-locked Nd³⁺:YAG laser coincides with the energy of the main electron—hole (exciton) transition in colloidal CdSe/ZnS QDs and the effective self-diffraction of two laser beams arises on the induced diffraction grating.
