Abstract
In order to optimize communication and output stability of laser system, with linear approximation method and loss-noise model of single mode laser driven by colored pump noise and quantum noise whose real and imaginary part are cross-correlated, the steady-state mean intensity correlation function and signal-to-noise ratio (SNR) are calculated with an input additive periodic signal. The new physical quantity K is defined to describing output property of laser system. The maximums are existed between the relationship of K and net-gain coefficient, self-saturation coefficient, cross-correlated coefficient of real and imaginary part of quantum noise. That is the best match of the laser communication system. Also the decrease of noise intensity and increase of input signal frequency all can optimize the output property of laser system.
