A new method for the realistic modeling of ultrashort pulse amplification under conditions of strong gain saturation has been developed. Both the frequency dependence and the time dependence of the gain are properly taken into account. The method can, for example, be applied to chirped-pulse bulk and fiber amplifiers, but is not restricted to pulses with particular spectral or temporal properties.
