9B9 - The theory of semiconductor lasers with consideration of saturation effects

Semiconductor behavior in strong fields having a frequency close to the absorption band is considered. It is proved that only the slowing down and recombination times of four different relaxation times are of importance for weaker fields. In this case, equality of Fermi-level electron and hole quasi-levels to light quantum energy corresponds to a saturation condition. A semiconductor absorption coefficient regarding saturation is calculated.
