# High-harmonic generation from plasma mirrors at kilohertz repetition rate

Abstract : We report the first demonstration of high-harmonic generation from plasma mirrors at a 1 kHz repetition rate. Harmonics up to nineteenth order are generated at peak intensities close to 10$^{18}$ W=cm$^2$ by focusing 1 mJ, 25 fs laser pulses down to 1:7 $\mu$m FWHM spot size without any prior wavefront correction onto a moving target. We minimize target surface motion with respect to the laser focus using online interferometry to ensure reproducible interaction conditions for every shot and record data at 1 kHz with unprecedented statistics. This allows us to unambiguously identify coherent wake emission as the main generation mechanism
