Airy beams were initially predicted in 1979 by two scientists, Michael Berry and Nandor Balazs, within the context of quantum mechanics. The scientists theorized the existence of a free particle ...

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 ...

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 ...

If you shine a beam of light from a laser or flashlight, the beam will spread out over distance, becoming wider and less intense far from the source. That phenomenon is called diffraction, and it is ...

As we all know, light on its own tends to travel in a straight line. When it gets sent through an aperture like a flashlight, diffraction occurs, which causes the beam to widen and lose its intensity.

Generating 3D light packets that propagate without dispersing in time or space is not an easy task. Andy Chong from Cornell University told Nature Photonics how he and his co-workers came up with a ...

Place the laser on top of the lab jacks, making sure the laser is pointed away from people. Place the slide mount on the optical rail and insert the sample slide to the slide mount. Plug in the laser ...

Conventional diffraction theory breaks down at sufficiently high X-ray intensities, such as that achieved with the latest generation of X-ray lasers (XFELs), and in this regime it is possible for an X ...

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