摘要：
The paper describes that the processing mehtod using constant carrier lifetime approximation in investigating the dynamic process of amplifying light pulse with semiconductor light amplifier is unreasonable. Through considering the practical composite mechanism of carrier in amplifier, the time domain distribution of the pulse after the pulse data stream passing through the amplifier is simulated by a numerical method and is compared with the results obtained with constant carrier lifetime approximation. The results show that these two have an obvious difference.
