Abstract: Maximum Lyapunov exponents and return maps are derived from a numerical integration of equations describing a laser with intracavity saturable absorber. Different sets of parameters are used in the models. It is shown that deterministic chaos with a small positive Lyapunov exponent is associated to multibranched return time return maps while noisy evolution leads to maps with a lattice structure.
