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 ...

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 ...

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 ...

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 ...

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 ...

Femtosecond vortex beams are of great scientific and practical interest because of their unique phase properties in both the longitudinal and transverse modes, enabling multi-dimensional quantum ...

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 ...

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 ...
