| Abstract: | The stationary probability density for the Langevin equation of two-noise-resources system where the noise corresponds to the weak intensity(D_i)approx-imation for Ornstein-Uhlenbeck(OU)noise has been driven by use of Likc-WKB method for analysing threedimensional Fokker-Planck equation(FPE).The influence on the nonequilibrium transitions is investigated.As an example,it is shown that the spontaneous emission noise and pump noise in one-mode dyelaser model will influent the stationary state properaties on laser radiation. |
