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 electron…

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…
