Zeptosecond and sub-mrad control of quantum equivalent non-local XUV pulses
ORAL
Abstract
Through the application of intertwined wavefronts to an intense femtosecond pulse we can create two XUV pulses that are separated in space and yet have a phase jitter of 0.1mrad or 6zs at 80nm center wavelength. High harmonic generation creates XUV pulses between the 7th and the 17th harmonic of the fundamental 800nm . We perform single- and two-photon interferometric experiments to show that each photon carries the full high harmonic spectrum. This was established by collapsing the wavefunction of a photon and easuring spectrally and spatially the second. The presence of spatial interference in this case, shows that while highly coherent, the two photons are not entangled. The delay between the pulses can be controlled with a resolution of 100zs. We discuss applications to molecular dynamics spectroscopy.
