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 ...

Electron and phonon are two fundamental particles (quasi-particles) of condensed matter and their interplay in single crystals can create many interesting physical phenomena, such as polariton, charge ...

Patent US 11,923,101 B2 describes an optical tweezer phonon laser system and method designed to modulate the mechanical vibrations of an optically levitated mechanical oscillator to produce coherence.

(Nanowerk News) A team of international researchers led by engineers at Washington University in St. Louis has seen the light and now has a lasing system that produces “good vibrations.” They ...

(PhysOrg.com) -- Random lasing, Robin Kaiser tells PhysOrg.com, is like standard lasing, with a little bit of a twist: “You don’t know the direction the photons will go, as you do with a more standard ...

The electron-phonon coupling intensity is calculated by Huang-Rhys S factor and the phonon-assisted fluorescence lineshape is predicted numerically. A broadband lasing emission spectrum (1000-1280 nm) ...

A team of researchers has developed a way to use a light field to trigger a mechanical movement that will generate an acoustic wave. A team of international researchers led by engineers at Washington ...
