Abstract
A control mechanism of time-delayed feedback is designed to suppress the fluctuation of a single-mode laser. Using the small time delay approximation, the analytic expression of the stationary probability distribution function of the single-mode laser filed is obtained. The mean, normalized variance and skewness of the steady-state laser intensity are calculated. It is found that the time-delayed feedback control can suppress the intensity fluctuation of the laser system. Matlab is used to perform numerical simulation and the results accord with the approximate analytic results.
