We describe a compact, reliable, high-power, and high-contrast noncollinear optical parametric chirped-pulse amplifier system. With a broadband Ti:sapphire oscillator and grating-based stretching and compression, the chirped pulses are amplified from 0.1 nJ to 122 mJ in type-I $$beta$$-barium borate optical parametric chirped pulse amplifiers with a total gain of over 10$$^{9}$$ at 10 Hz repetition rate. Pulse compression down to 19-fs duration achieved after amplification indicates a peak power of 3.2 TW at an average power of 0.62 W. The pre-pulse contrast is measured to be less than 10$$^{-8}$$ on picosecond timescales.
