Abstract
Since the Lorenz model has been applied to single-mode laser oscillation,1 the most important problem is how to detect, control, and experimentally observe the occurrence of chaos in optical systems.2-3 The predication of chaos for the high superthreshold γ = Δ0/Δs ≥ 9 in a bad cavity (σ ≥ 2) makes the demonstration very difficult.2 As for the influence of detuning δc between the atomic frequency ω0 and the cavity frequency ωc on the properties of the laser second threshold, for temporal perturbation analytic results show that the bi- furcation leads to an unstable small-amplitude limit cycle for small detuning and to a stable small-amplitude limit cycle for large detuning.4–6
