Approximate Calculation of Two-Dimensional Colored Noise in a Laser Field
Functional derivation is employed to analyze the two-dimensional colored noise in the third-order laser model. The stationary intensity distribution is derived. The variation of the most probable intensity with pump parameter and noise intensity correlation time is investigated. With the shifted 1/N expansion, the instantaneous solution of the laser model, i.e., the change of eigenvalues with the pump parameter, is obtained. It is shown that the pump parameter and intensity noise correlation time are the major factors of the first-order-like transition. Angular noise correlation time has great influence on the linewidth in the intensity spectrum.
