An averaging method valid for strongly nonlinear oscillators is used for the first time to describe the pulsating intensity
regimes of semiconductor lasers subject to injection. Slow-time equations are derived which are valid for solutions of arbitrary
amplitude. These averaged equations do not require the knowledge of a particular bifurcation point and are a good starting
point for further analysis. Bifurcation points to periodic or quasiperiodic intensity oscillations are determined analytically by
exploring certain limits of the parameters. Finally, we illustrate the strength and weakness of these expressions by comparing
bifurcation diagrams obtained from the averaged equations and from the original laser equations.
