Starting from a fully microscopic spin-flip model for a vertical cavity surface emitting laser, we derive a macroscopic model that includes the frequency dependence of the complex gain and the gain nonlinearities due to spectral hole burning. The macroscopic model reproduces well the predictions of the microscopic one. The gain nonlinearities affect especially the switching from the higher to the lower frequency, and their effects are more manifest when the spin-flip rate is large.
