X-ray driven displacive excitation of coherent phonons
Oleg Dogadov, Remi Claude, Christoph Emeis +29
Modulating electron-phonon coupling offers a route to control structural displacements and tune material functionality. Valence-to-conduction band transitions, however, provide lim…
Spin waves excited by hard x-ray transient gratings
Peter R. Miedaner, Alexei A. Maznev, Mykola Biednov +49
Recent progress in ultrafast x-ray sources helped establish x-rays as an important tool for probing lattice and magnetic dynamics initiated by femtosecond optical pulses. Here, we…
Resonant Self-Diffraction of Femtosecond Extreme Ultraviolet Pulses in Cobalt
Alexei A. Maznev, Wonseok Lee, Scott K. Cushing +14
Self-diffraction is a non-collinear four-wave mixing technique well-known in optics. We explore self-diffraction in the extreme ultraviolet (EUV) range, taking advantage of intense…
Structured illumination microscopy with extreme ultraviolet pulses
R. Mincigrucci, E. Paltanin, J. -S. Pelli-Cresi +13
The relentless pursuit of understanding matter at ever-finer scales has pushed optical microscopy to surpass the diffraction limit and produced the super-resolution microscopy whic…
A high-efficiency programmable modulator for extreme ultraviolet light with nm feature size based on an electronic phase transition
Igor Vaskivskyi, Anze Mraz, Rok Venturini +11
The absence of efficient light modulators for extreme ultraviolet (EUV) and X-ray photons significantly limits their real-life application, particularly when even slight complexity…
Transient grating spectroscopy on a DyCo thin film with femtosecond extreme ultraviolet pulses
Victor Ukleev, Ludmila Leroy, Riccardo Mincigrucci +11
Surface acoustic waves (SAWs) are excited by femtosecond extreme ultraviolet (EUV) transient gratings (TGs) in a room-temperature ferrimagnetic DyCo alloy. TGs are generated by…
Nanoscale transient polarization gratings
Laura Foglia, Björn Wehinger, Giovanni Perosa +24
We present the generation of transient polarization gratings at the nanoscale, achieved using a tailored accelerator configuration of the FERMI free electron laser. We demonstrate…
Stimulated Brillouin scattering at 1 nm-1 wavevector by extreme ultraviolet transient gratings
Danny Fainozzi, Laura Foglia, Riccardo Mincigrucci +4
We crossed two femtosecond extreme ultraviolet (EUV) pulses in a beta - Ga2O3 (001) single crystal to create transient gratings (TG) of light intensity with sub-100 nm spatial peri…
Ultrafast dynamics in (TaSe)I triggered by valence and core-level excitation
Wibke Bronsch, Manuel Tuniz, Giuseppe Crupi +16
In this work, we study the out-of-equilibrium dynamics of the paradigmatic quasi-one-dimensional material (TaSe)I, that exhibits a transition into an incommensurate CDW pha…
