Lasers are a significant historical invention with ubiquitous impact in society. The concept also has interdisciplinary applications as phonon lasers and atom lasers. A laser in one physical domain can be pumped by energy ...
Since the introduction of the first ruby laser—a solid-state laser that uses the synthetic ruby crystal as its laser medium—in 1960, the use of lasers has expanded significantly in scientific, medical and industrial fields.

Researchers at Johannes Kepler University in Linz have been investigating the physical properties of Cu(110), a surface attained when cutting a single copper crystal in a specific direction, for several years. Their most ...
Intense mid-infrared excitation has been demonstrated as a powerful tool for controlling the magnetic, ferroelectric and superconducting properties of complex materials. Nonlinear phononics is key to this end, as it displaces ...
