Sustained relaxation oscillations and irregular spiking have been observed in many periodically modulated lasers. These observations have been substantiated numerically by recent studies of the laser rate equations. In this paper, we propose a new asymptotic analysis of the laser equations which assumes that the laser oscillations correspond to relaxation oscillations. We identify a large parameter and construct these periodic solutions using perturbation techniques. We obtain the equations for the Poincare map and determine the first period doubling bifurcation.
