Pulse-contrast degradation at the CPA-system's output is analyzed. If Kerr-nonlinearity is present, weak initial spectral phase and amplitude modulations are responsible for the decrease. The pulse is split into several sub-pulses. Besselfunctions describe the intensities of the side-pulses relative to the principal pulse. We provide the governing physica quantities.
