Enhancement of the Petawatt laser "LFEX" [1] up to 2,000 trillion watts for one trillionth of one second. High power output implemented by a 4-beam amplifier technology and the world's highest ...

Using a handful of inexpensive components -- including an off-the-shelf computer webcam and a small diffraction grating, a device for splitting and diffracting light into several beams -- researchers ...

Micromachining can be used to create a infra-red beam-forming phased array, according to engineers at University of California, Berkeley, who have made a 160 x 160 array on a 3.1 x 3.2mm die that can ...

In a physics first, a team including scientists from UB and the National Institute of Standards and Technology (NIST) has created a way to make beams of neutrons travel in curves. These Airy beams ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

Airy beam: When an ordinary beam of neutrons strikes the team’s silicon grating, the millions of scored lines on the grating convert the neutrons into an Airy beam with a wavefront that travels along ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...
