Abstract
We present a two-stage noncollinear optical parametric chirped-pulse amplification system that generates pulses containing of energy at an central wavelength and repetition rate. These light pulses are compressed to within 5% 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 , , and at , , and , respectively. This source allows for experiments in a regime of relativistic light–matter interactions and attosecond science.
