| Abstract: | We have detected the stochastic resonance(SR) phenomenon by studying the output signal-to-noise ratio (SNR) of the linear model of single-mode laser, which is driven by two color noises correlated in the form of an exponential function. Moreover, we also discuss the influence on SNR from the noise (noise intens ity, correlated strength and correlation time between noises) and signal (signal frequency and signal amplitude). |

| Keywords: | stochastic resonance noise correlation time signal-to-noise rate |
