In this work we present a new method for peak-power scaling in nonlinear CPA-systems. By clipping the tails of the spectrum we demonstrate pulse quality enhancement and an increase of peak-power at the output of the CPA-system. A theoretical model allows us to determine an optimal ratio between the spectral clipping bandwidth and the pulse bandwidth at a certain B-integral. Additionally, a simple redesign of a grating based stretcher unit, applying our new spectral clipping technique, would significantly increase the output peak-power of such nonlinear CPA-systems by a factor up to six due to the higher stretching ratio.
