Characteristic features associated with the presence of non-white pump noise in single and two-mode dye lasers are discussed. A slow initial decay of the steady state intensity correlation function is characterized in terms of an effective eigenvalue which is calculated exactly. For the single mode case, non-white pump noise produces a large reduction of its value and suppresses the existence of a minimum. For the two-mode case the crossed-correlation effective eigenvalue becomes non zero due to pump noise when the two pump parameters are different. Transient statistics for the single mode case are characterized by the passage time distribution and the anomalous fluctuations. The mean first passage time is essentially independent of pump noise while the variance is enlarged by pump noise but partially reduced by its nonwhite character. Similar phenomenon is observed in the anomalous fluctuations.
