摘要：

A coherently excited exciton-biexciton system under the action of a non-resonant pump field is analysed within the framework of the Hartree-Fock-Bogolyubov theory. The excitation spectra, which consist of optical absorption and gain, are determined. It is pointed out that the optical gain is greatly enhanced through the giant oscillator strength effect of biexcitonic molecules. Numerical examples for CuCl are also presented.
