| Abstract: | In this paper, stochastic resonance(SR) phenomenon is discussed by studying the initial state output signal-to-noise(SNR) of the linear model of single-mode laser, which driven by two white noises correlated in the form of a exponential function and the first periodic stochastic resonance of the instantaneous-state is calculated .Moreover the influence on SNR is discussed by correlated strength and correlation time between noises and signal frequency. the stochastic resonance is detected under proper conditions and the steady-state stochastic resonance is compared . |
