Optical parametric chirped pulse amplification (OPCPA) is widely recognized as a key technique for producing intense few-cycle light pulses for attosecond science [1]. Owing to the continuous improvement of diode-pumped solid state (DPSS) lasers, the OPCPA technique is becoming ever more attractive as combining DPSS laser pump sources and OPCPA enables simultaneous scaling of peak and average power of few-cycle pulse trains. In this contribution, we present a table-top OPCPA system driven by diode-pumped Yb:KGW and Nd:YAG lasers, delivering ~3 cycle, CEP stabilized pulses with >53mJ energy at 1 kHz repetition rate, corresponding to >5.5 TW peak power and >53 W average power. To the best of our knowledge, this is currently the highest average power produced by a few cycle, TW-class OPCPA system.
