The effect of the excess noise on the laser operation of Fabry-Perot and distributed feedback (DFB) lasers is discussed. We use the semiclassical analysis based on the Fokker-Planck equation corresponding to the set of coupled Langevin equations. The stationary and nonstationary solution of the single-mode operation is obtained. Numerical results reveal the excess noise factor as well as the influence of the excess noise on the intensity fluctuations and the laser linewidth for different laser systems.
