Multi-W, 100-kHz, few-cycle mid-infrared source with sub-100-mrad single-shot carrier-envelope phase noise

摘要

dependency of the ponderomotive energy, shorter pulses lead to the higher peak intensities enhancing the HHG conversion yield and extending HHG cutoff energy even further. Additionally, few-cycle driving pulses reduce the number of produced attosecond bursts up to, ideally, a single isolated attosecond pulse. In this case, CEP stability and control is paramount for ensuring optimization and shot-to-shot reproducibility of the HHG yield and spectra.
