Using linear approximation method, we calculate the intensity correlation time of a single-mode laser driven by both colored pump noise with signal modulation and quantum noise with cross-correlation between its real and imaginary parts, and analyze the influence of the signal, noise and its cross-correlation form on the statistical fluctuation of the laser system. We detect that the "color" of pump noise is an important factor that affects the statistical fluctuation of the laser system. When the colored pump noise is short time correlation, within a determinate parameter range, the intensity correlation time can be prolonged, and the statistical fluctuation of the laser system can be restrained by increasing the amplitude of modulation signal. The specific frequency of input signal will result in intensity correlation time to appear maximum, and the statistical fluctuation of the laser system is least here. When the colored pump noise is long time correlation, within a determinate parameter range, the intensity correlation time can be also prolonged by increasing the frequency of modulation signal and decreasing its amplitude, and the statistical fluctuation of the laser system will decrease. In particular, when the intensity of quantum noise increases and the cross-correlation between its real and imaginary parts enhance, the intensity correlation time will prolong, and the statistical fluctuation of the laser system is restrained.

The output power and the signal-to-noise ratio (SNR) of a single-mode laser system are calculated in the case of the laser model with periodically modulated noise. The corresponding stochastic resonance (SR) phenomena are discussed and compared with the case without periodically modulated noise. It is shown that the main difference between the two noise laser models exists in the SNR as a function of signal period. There appears resonance and suppression coexisting phenomenon for the model with periodically modulated noise, which can be utilized to restrain or optimize the output SNR of the system. Whereas, SR is absent for the model without periodically modulated noise, and the SNR just increases monotonously with signal period.

The effects of the correlations between real and imaginary parts of the quadratic pump noise on the normalized intensity correlation function and the associated relaxation time of a single-mode laser model were investigated. The expressions of the intensity correlation function C(s) and the relaxation time Tc were derived. Based on numerical computations, we found that Tc monotonously increases as the strength λp of correlation between the real and imaginary parts of quadratic pump noise increases and the larger λp value is, the slower C(s) decays. The presence of correlations between the real and imaginary parts of the quadratic pump noise causes the intensity fluctuation to increase.
