A microscopic laser model was validated on the basis of the quantum kinetic equations using the experimentally determined gain, threshold current, quasi-Fermi level separation data and spontaneous emission taken on GaInP/AlGaInP lasers. By comparing calculated and experimental optical properties, a significant contribution to the threshold current was found from the non-radiative recombination within the quantum wells. A graph of calculated absorption spectra as a function of carrier density was also plotted.
