STEADY-STATE ANALYSIS OF 2 SINGLE-MODE DYE-LASER MODELS WITH MULTIPLICATIVE COLORED NOISE

In this paper, a unified expansion theory that can be simultaneously applied to both large and small correlation times developed by Gang HU is established and applied to the systems driven by multiplicative colored noise. The stationary intensity probabilities are calculated for colored gain-noise and colored-loss-noise models. Comparing with the predictions of the best Fokker-Planck equation and the unified colored-noise approximation for the stationary intensity probability of the two models, it is found that the results of the unified expansion theory are in better agreement with simulations and experimental results than those of the best Fokker-Planck equation approximation and the unified colored-noise approximation.
