We explore some general dynamical properties of a homogeneously broadened ring laser driven by an external coherent signal. By combining the information obtained from time-dependent solutions, their power spectra, Poin-caré surface of sections, and Lyapunov exponents, we provide detailed evidence of the bifurcation structure of a laser with injected signal under high-gain conditions and show the existence of up to three basins of attraction for the same range of operating parameters. We also discuss the behavior of this system for experimentally accessible ranges of the gain and provide evidence for the persistence of a number of interesting pulsation phenomena.
