Direct measurement of non-equilibrium phonon occupations in femtosecond laser heated Au films
T. Chase, M. Trigo, A. H. Reid +9
We use ultrafast electron diffraction to detect the temporal evolution of phonon populations in femtosecond laser-excited ultrathin single-crystalline gold films. From the time-dep…
How to distinguish squeezed and coherent phonons in femtosecond x-ray diffuse scattering
T. Henighan, M. Trigo, M. Chollet +9
Impulsive optical excitation can generate both coherent and squeezed phonons. The expectation value of the phonon displacement oscillates at the mode frequency for the cohe…
Generation of high-frequency strain waves during femtosecond demagnetization of Fe/MgO films
T. Henighan, M. Trigo, S. Bonetti +22
We use femtosecond time-resolved hard x-ray scattering to detect coherent acoustic phonons excited during ultrafast laser demagnetization of bcc Fe films. We determine the lattice…
Phonon Spectroscopy with Sub-meV Resolution by Femtosecond X-ray Diffuse Scattering
Diling Zhu, Aymeric Robert, Tom Henighan +5
We present a reconstruction of the transverse acoustic phonon dispersion of germanium from femtosecond time-resolved x-ray diffuse scattering measurements at the Linac Coherent Lig…
