By adding periodic signal into two-mode laser, we take the first-order approximation to the multiplication noise of the laser intensity equation, and use a linear approximation to calculate the correlated function and power spectrum. We find that the signal-to-noise ratio presents stochastic resonance as the intensities of pump noise and quantum noise and the frequency of signal vary.
