High energy, ultrashort pulses are widely used for strong field physics experiments such as laboratory astrophysics , high energy density physics , schemes for particle acceleration , among others. Most of these experiments require ultrashort laser pulses with the PW peak power. One of the methods to generate those pulses is Optical Parametric Chirped Pulse Amplification (OPCPA) [4,5]. The main advantages of the OPCPA are the high single pass gain, lower thermal effects as well as ability to support amplification of broad spectrum , which are crucial elements to generate intense pulses at higher repetition rate.
