When people are thinking of the future of space travel, an idea that floats around is a spaceship with a giant solar sail pushed along by a massive laser. Inspired by the concept but lacking a giant ...

A new laser based on a swirling vortex of light has been created by physicists in the US. The “topological-defect laser” could be a useful addition to lab-on-a-chip devices, where it could manipulate ...

Deep ultraviolet (DUV) lasers, known for their high photon energy and short wavelengths, are essential in various fields such as semiconductor lithography, high-resolution spectroscopy, precision ...

Scientists at the Stanford Linear Accelerator Center (SLAC) have devised a new way of creating twisted laser beams -- optical vortexes -- for carrying vast, near-infinite amounts of data down optical ...

BUFFALO, N.Y., July 29 (UPI) --As the rise car ownership and automobile use in the 1950s and 60s necessitated bigger, better roads, increasing broadband use demands more efficient telecommunications ...

Twisting laser patterns into a corkscrew-like pattern, rather than sending the light beams in a line, promises to relieve some data gridlock, say scientists A bottleneck in data rates is coming, some ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...

Laser vortex beams can exchange their optical angular momentum with a plasma from which they are reflected. Laser beams with vortex-shaped wave fronts carry orbital angular momentum that can be used ...
