(PhysOrg.com) -- Researchers at Yale University have succeeded in building a new kind of laser based on the way brightly colored birds show their colors. Building on the new approach to creating laser ...

(Nanowerk News) Dielectric optical microresonators confine and concentrate light in a tiny circular path due to multiple near total internal reflections at the curved dielectric-air interface, where ...

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 ...

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 ...

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 ...

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 ...

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 ...

(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 ...

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 ...

New research shows that lasing for over one hour at room temperature can be achieved from low-cost quasi-2D perovskite materials by properly managing losses caused by triplet excitons. This new ...
