560 TW peak power has been achieved experimentally using a Cr:forsterite master oscillator at 1250 nm, a stretcher, three optical parametrical amplifiers based on KD*P crystals providing 38 J energy in the chirped pulse at 910 nm central wavelength and a vacuum compressor providing 43 fs pulse duration. To our knowledge, it is a world record OPCPA system and one of the five most powerful laser systems currently available.
