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 ...

A directional random laser mediated by transverse Anderson localization in a disordered glass optical fiber is reported. Previous demonstrations of random lasers have found limited applications ...

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, ...

Modern technologies increasingly rely on light sources that can be reconfigured on demand. Think of microlasers that can ...

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 ...

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 ...

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 ...
