Pulse broadening is observed for the amplification of a 2.2 ps pulse by a semiconductor laser traveling-wave amplifier when the input pulse energy is well below the saturation energy of the amplifier. The broadening is found to be much larger than that predicted on the basis of homogeneous gain saturation. It is shown from a traveling-wave rate equation simulation that the nonlinear gain compression is responsible for such a large temporal broadening.
