As a pump source for intense few-cycle laser system with optical-parametric chirped-pulse amplification (OPCPA), we have been developing cryogenically-cooled Yb:YLF chirped-pulse amplification laser. So far we have successfully obtained high energy output pulse with 107 mJ of energy from a single-stage regenerative amplifier, which can be compressed to 2.2 ps in duration without pedestal. An adaptive phase control of laser pulse is underway for indirect dispersion compensation of generated idler pulse on OPCPA.
