%X Femtosecond pulse was directly amplified by self similar parabolic amplifier,and the amplified pulse was then compressed with a photonic bandgap fiber with low nonlinearity.The influences of initial pulse width and the chirp of femtosecond pulse on its self similar amplification and succedent compression were studied by Split-step Fourier Method.The result shows the wider the pulse is,the worse the self similar evolution and compression are; consequently the compressed pulse has a wider pulse width and is also accompanied by a pedestal.It also shows the initial chirp can greatly hold out the self similar evolution,and deteriorate compression quality.And the larger the initial chirp,the worse the self similar evolution.Positive chirp has a larger influence on the self similar evolution than negative chirp.
