By adding modulated wave to the equation of the laser intensity of the gain-noise model of the single-mode lasers, we use the linear approximation method to calculate the power spectrum and signal-to-noise ratio(SNR) of the laser intensity, which is driven by two white noises correlated in the form of δ function. The result show that the SNR shows stochastic resonance with the varing of not only intensities of the pump noise and quantum noisebut also the frequency of a high frequency carrier signal and frequency of a low frequency periodical signal.
