| Abstract: | In this paper,the effects of cross-correlations between the real and imaginary parts of quantum noise on the laser intensity in a saturation laser model are studied.An approximate Fokker-Planck equation and analytic expressions of the steady-state probability distribution function(SPD)of the laser system is derived.The results indicate that the cross-correlations between the real and imaginary parts of quantum noise increases the laser intensity fluctuations. |
