The optoelectronic properties of topological insulators have many attractions, including a robustness to defects, imperfections and sharp corners. This robustness inspired a group of scientists to ...

Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the ...

Researchers report on having achieved a solution-processed infrared laser at room temperature compatible with CMOS technology and tunable to emit in the telecommunications window. Lasers, devices that ...

Suppression of long-lived energetic states called triplet excitons shown to be key for preventing the "lasing death" that has been limiting long operation An international team of researchers led by ...

When a water droplet interacts with a surface to form a contact angle, the interfacial molecular forces determine the geometry of a droplet resonator. Dramatic mechanical changes at the interface play ...

A layer of perovskite is shown lasing green under continuous operation at room temperature. Credit: Chuanjiang Qin, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences On paper, ...

The team's experimental setup: Atoms are cooled and slowed inside a vacuum chamber, until they can be trapped in a lattice inside a cavity (black triangular cavity spacer in the bottom half of the ...

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 ...

A Los Alamos National Laboratory team has overcome key challenges toward technologically viable high-intensity light emitters based on colloidal quantum dot technology, resulting in dual-function ...

(Nanowerk News) Tiny molecular forces at the surface of water droplets can play a big role in laser output emissions. As the most fundamental matrix of life, water drives numerous essential biological ...
