A design for generation of two ultra-high power laser beams, 130 TW and 1.4 PW, using a chain of optical parametric chirped pulse amplifiers, first pumped by a 10 Hz frequency doubled Nd:YAG laser, and later by the frequency tripled single-shot kilojoule level iodine laser Prague Asterix Laser System is presented. Expected enhancement of the parameters in the upgrade, besides the output power, are up to 1022 W/cm2 from 1016 W/cm2 in target intensity, and about 20 fs from 0.5 ns in pulse duration. Owing to the limited dimensions of the Prague Asterix Laser System building, the lay-out of the new equipment had to use only the left-over space in the laser hall.
