A fully microscopic model is used to calculate the carrier losses in semiconductor lasers due to Auger recombination and spontaneous emission. The results show that the commonly assumed power-law dependencies of these loss processes on the plasma density break down already below the transparency point. Most significantly, the density dependent increase of the spontaneous emission changes from quadratic to linear, while the increase of the Auger recombination is reduced from cubic to approximately quadratic or even less.
