An international team of researchers led by Kyushu University and Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, has demonstrated stable, continuous lasing at room temperature ...

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 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 ...

Combining photonics and electronics would bring the advantages of speedy optical data transfer to the increasingly miniaturized world of electronics. Ideally photonics and electronics elements would ...

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 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 ...

The air force says the incidents, which involve commercially available laser pointers, pose a significant safety risk to aircraft and crew. The US Air Force (USAF) is dealing with what the service ...

This study is led by professor Tianrui Zhai (Faculty of Science, Beijing University of Technology). The fiber braiding cavity is designed to achieve the red-green-blue (RGB) whispering gallery mode ...

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 ...

(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 ...
