摘要： In this article, we present a theoretical description of the various effects on femtosecond light pulse during its propagating through a long solid gain medium on the basis of Maxwell equations and rate equations, By numerical simulation, we analyzed the variation of pulse energy, pulse duration. pulse shape and spectral distribution due to gain saturation, spectral narrowing, phase-shift induced by gain, group-velocity dispersion and self-phase modulation.
