摘要

We present a two-stage noncollinear optical parametric chirped-pulse amplification system that generates 7.9 fs pulses containing 130 mJ of energy at an 805 nm central wavelength and 10 Hz repetition rate. These 16 TW light pulses are compressed to within 5percent of their Fourier limit and are carefully characterized by the use of home-built pulse diagnostics. The contrast ratio before the main pulse has been measured as 10~(-4), 10~(-8), and 10~(-11) at t(velence)-3.3 ps, t(velence)-5 ps, and t(velence)-30 ps, respectively. This source allows for experiments in a regime of relativistic light-matter interactions and attosecond science.
