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…
Femtosecond self-diffraction as a measure of the nonlinear response spectrum
Luca Assogna, Giovanna Salvitti, Matteo Silvestri +11
Self diffraction is a four-wave mixing process proportional to the square modulus of third-order nonlinearity susceptibility , which is related to the material's electroni…
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…
X-ray Circular Dichroism measured by cross-polarization X-ray Transient Grating
Jeremy R. Rouxel, Riccardo Mincigrucci, Danny Fainozzi +1
Measuring natural circular dichroism in the X-ray regime to extract stereochemical information from chiral molecules in solution remains a challenge. This is primarily due to techn…
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…
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…
BGO relaxation dynamics probed with heterodyne detected optical transient gratings
Danny Fainozzi, Sara Catalini, Renato torre +2
We used optical laser pulses to create transient gratings (TGs) with sub-10 μm spatial periodicity in a Bismuth Germanate (310) (Bi4Ge3O12) single crystal at room temperature. The…
