Abstract

Two-photon excitation spectrum of the luminescence emitted in the A//T band follows the A band lineshape but reveals a feature, not present in one-photon spectrum, due to the forbidden **1A//1//g yields **3A//1//u transition. The cross section of the process indicates that two-photon transitions are indirect ones, allowed by phonons. The dependence of the emitted light density on the direction of polarization of the exciting photons makes it possible to idenfity the symmetry of the transitions.
