A model for a laser with periodically modulated injected signal in the limit of gain approximately equal to the losses, is presented. By means of the normal-form theory we characterize its dynamical behaviors arround of a Hopf bifurcation point, taking into account fluctuations in intensity and frequency of the injection also. We determinate the spectral contributions when the Hopf frequency is or it is no coincident with the modulation frequency of the injected signal.
