【Abstract】 According to the linearized equation of single-mode la ser, the correlated function of the laser intensity was calculated. The instanta neous-state stochastic resonance of the linear model of single-mode laser driv en by two white noise correlated in the form of aδfunction was studied. The fir st periodic power spectrum and signal-to noise rate of the instantaneous-state were calculated. The stochastic resonance under proper conditions was detected and it was compared with the steady-state stochastic resonance.更多还原
