  1. 226. Fully structured light with seeded free-electron lasers (FRAI01)

    Advanced FEL modes and science applications
    Invited Oral Presentation

    Light with precisely tailored structure in all degrees of freedom is called fully structured light. We present an experimental demonstration of coherent FSL EUV light with the `star’ type polarization topology at the FERMI free electron laser (FEL) in Trieste, Italy. Control of the polarization is obtained through the overlap of radiation emitted in orthogonally polarized helical undulators...

  2. 177. X-ray FEL lays the groundwork for Scandium-45 nuclear clock (FRAI02)

    Advanced FEL modes and science applications
    Invited Oral Presentation

    Precise timekeeping is indispensable in everyday life, science, and technology. It relies on reference oscillators with stable frequencies. Atomic clocks -- the most precise time-measurement devices at present -- use spectrally very narrow resonant transitions between electronic states in atoms as their reference oscillators. With the advent of hard x-ray FELs, the use of extremely narrow...

  3. 69. Experimental demonstration of attosecond pump–probe spectroscopy with an X-ray free-electron laser (FRAC03)

    Contributed Oral Presentation

    Pump–probe experiments with subfemtosecond resolution are the key to understanding electronic dynamics in quantum systems. Here we demonstrate the generation and control of subfemtosecond pulse pairs from a two-colour X-ray free-electron laser. By measuring the delay between the two pulses with an angular streaking diagnostic, we characterize the group velocity of the X-ray free-electron laser...

  4. 121. Demonstration of tunable, phase-locked X-ray FEL pulses (FRAC04)

    Advanced FEL modes and science applications
    Contributed Oral Presentation

    The availability of coherent copies of free-electron laser (FEL) X-ray pulses with tunable delay will facilitate a realm of techniques, such as the X-ray analogue of Fourier transform infrared (FTIR) spectroscopy, and accelerate the development X-ray quantum optics. Here we report steps toward phase-locked, tunable X-ray FEL pulses by combining the self-seeding mechanism, the slotted foil...
