Possibility of a parametrical resonance when investigating optical properties of the semiconductors in exciton range of spectrum

Abstract

The results of the theoretical investigation of the semiconductor susceptibilities in the frame of pump–probe approach are presented using the exciton–photon and exciton– exciton interaction. The strong pump beam excitates excitons.The excitons interact with each other and the weak laser pulse with the frequency tuned to the exciton transition tests the optical properties of a semiconductor.
