Abstract
We present a new third-order non-linear solid-state cleaner for
temporal femtosecond pulses. This filter is based on cross-polarized
wave generation in non-linear crystals. The contrast reaches
10-10 for millijoule input pulse. The method is reliable enough
to solve the contrast issue for Petawatt class lasers.
