Organic solid-state lasers are essential for photonic applications, but current-driven lasers are a great challenge to develop in applied physics and materials science. While it is possible to create charge transfer complexes ...
Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly different spiral shape, may ...
(Phys.org)—Nanophotonics, which takes advantage of the much faster speed of light compared with electrons, could potentially lead to future optical computers that transmit large amounts of data at very high speeds. Working ...
(Phys.org) —In an atom laser, millions of individual atoms propagate through space with minimal spreading, just like photons propagate in a coherent photon laser beam. Although both types of lasers are similar, atom lasers ...
(Phys.org) -- Although pointing high-energy lasers at the sky to cause pouring rain is currently a high-tech dream, the motivation behind controlling the weather has existed since the days of our ancient ancestors. Throughout ...
(PhysOrg.com) -- Building a nuclear gamma-ray laser has been a challenge for scientists for a long time, but a new proposal for such a device has overcome some of the most difficult problems. In the new study, Eugene Tkalya ...
(PhysOrg.com) -- Although lasers come in all shapes and sizes, one of the most recent laser designs is especially intriguing, since it’s made of just a single nanowire. Due to its small size and simplicity, the single-nanowire ...
(PhysOrg.com) -- "Several groups have been using direct laser writing since the end of the 1990s," Michael Thiel tells PhysOrg.com. Thiel is a scientist has been working at the Karlsruhe Institute of Technology (KIT) in Germany. ...
Using a specially designed 3D printed vacuum system, scientists have developed a way to "trap" dark matter with the aim of detecting domain walls. This will be a significant step forwards in unraveling some of the mysteries ...
An international team of scientists has developed a novel way to experimentally produce plasma 'fireballs' on Earth.
