By using the linear approximation method, the normalized intensity fluctuation was calculated in a gain-noise model of a single-mode laser driven by colored correlated noises, and the influences of the parameters of the noises and modulation signal normalized intensity fluctuation were studied. The results showed that the normalized intensity fluctuation was strongly dependent on self-correlation times of the pump and quantum noises and the ratio of them.
