By means of linear approximation method, we derive and discuss the intensity correlation function, correlation time, and power spectrum for the gain noise model of a single mode laser driven by multiplicative colored and additive white noises with δ correlation form. It is found that: (1) The negative correlation between noises makes the evolution of the intensity correlation function with the time showing two forms: the monotonic attenuation and presence of the positive maximum value; while corresponding to all points on the critical line of the parameter graph for illustrating two forms, the evolution curve of the intensity correlation function with the time exhibits the initial plateau. (2) Due to the existence of the negative correlation between noises, an obvious character for the change of the intensity correlation time with the pump noise strength is that it has a crest value, and the relaxation process of the laser is slower down than that of two independent noises. (3) The power spectrum exhibits only one peak.
