In this review we address the microscopic mechanisms that are involved in the
photogeneration processes of GHz–THz coherent acoustic phonons (CAP) induced by an …

Understanding and controlling vibrations in condensed matter is emerging as an essential
necessity both at fundamental level and for the development of a broad variety of …

The aim of this article is to provide an introduction to picosecond laser ultrasonics, a means
by which gigahertz–terahertz ultrasonic waves can be generated and detected by ultrashort …

Generation of strain using light is a key issue for future development of ultrasonic devices.
Up to now, photo-induced GHz–THz acoustic phonons have been mainly explored in metals …

Ultrashort light pulses induce rapid deformations of crystalline lattices. In ferroelectrics,
lattice deformations couple directly to the polarization, which opens the perspective to …

Coherent phonons can be launched in materials upon localized pulsed optical excitation,
and be subsequently followed in time-domain, with a sub-picosecond resolution, using a …

The control of optically driven high-frequency strain waves in nanostructured systems is an
essential ingredient for the further development of nanophononics. However, broadly …

We realize resonant driving of the magnetization precession by monochromatic phonons in
a thin ferromagnetic layer embedded into a phononic Fabry-Pérot resonator. A femtosecond …

Transmission electron diffraction is naturally sensitive to the detection of shear-type
deformations in single-crystalline structures due to the effective tilting of the lattice planes …

The control of acoustic phonons, which are the carriers of sound and heat, has become the
focus of increasing attention because of a demand for manipulating the sonic and thermal …
