In this paper, we deduce the equations of motion for both cw and long-pulse light in active fibers. We then solve the equations under zero-order and first-order perturbations by using the quantum theory about the polarization of an active material. We give a quantitative description of the evolutions of amplitudes and phases of the cw and long-pulse light, and discuss the influence of the active material on the group velocity of the long pulse light.
