Abstract

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 β-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 prepulse contrast is measured to be less than 10 8 on picosecond time scales.
