The presented optical parametric chirped pulse amplification （OPCPA） source currently delivers carrier-envelope phase （CEP）-stable 67-fs duration optical pulses with up to 18-μJ output energy at 160-kHz repetition rate. The focusability of the output beam （M^2 -2） enables peak intensities exceeding 1014 W/cm^2 and the record output energy stability-below 1% power fluctuation over 4.5 h makes this source a key enabler for the strong field physics community.展开更多
