In this paper, a novel amplifier setup as an additional stage for the CPA pump laser of a Petawatt system is presented. In this amplifier, 20 relay-imaged passes through an Yb:YAG active-mirror are realized. After compression 1 TW pulses with 740 fs duration are generated at a repetition rate of 2 Hz.
