Abstract
Measurements were made of the emission spectra of high-purity GaAs under intense excitations by a pulsed nitrogen laser at various pumping levels, applied electric fields and lattice temperatures. The results are explained quite well by considering that the radiative exciton-exciton collision processes to leave an exciton in various discrete and continuum states play the dominant role in both spontaneous and stimulated emissions.Keywords
