摘要

An optical parametric chirped-pulse amplification system is demonstrated to provide 32.9% pump-to-signal con-version efficiency. Special techniques are used to make the signal and pump pulses match with each other inboth spectral and temporal domains. The broadband 9.5-mJ pulses are produced at the repetition rate of 1 Hzwith the gain of over 1.9 × 108. The output energy fluctuation of 7.8% is achieved for the saturated amplificationprocess against the pump fluctuation of 10%.
