### Abstract

Starting from a set of equations derived from a microscopic theory we show that the familiar nonlinear gain of the form a/(1+I/I_{s}) introduced in semiconductor laser rate equations phenomenologically should be replaced by a more general form of a/(1+I/I_{s})^{b}. The new scaling exponent b depends on the relaxation constant γ_{T} that describes the rate of heat dissipation from plasma to the lattice due to carrier-phonon scattering.
