Spectral properties of high-order harmonic radiation enhanced by XUV-driven electron-hole dynamics
R. Esteban Goetz, Anh-Thu Le
We analyze the spectral properties of high-order harmonic radiation with photon energies extending beyond the regular cutoff energy in standard high-order harmonic generation. The…

Single photon zeptosecond interferometry
Geoffrey R. Harrison, Tobias Saule, R. Esteban Goetz +6
We demonstrate the generation of a train of attosecond XUV pulses that are in a superposition of wavefront states. Such superposition yields a high precision, self-referencing, com…
