Diffraction is normally stronger for narrow beams, which tend to spread out quicker than wider beams. Controlling diffraction would enable the realization of all-optical circuits and the efficient ...

Scientists hope their plumage project could someday lead to biocompatible lasers that could safely be embedded in the human ...

Shaped, diffraction-free electron beams would be extremely useful in tunneling electron microscopes (TEMs), commonly used to manipulate and image the surface properties of materials.

The output Bessel beam has very similar characteristics to those produced by axicons, but the fibre-based device is about three times smaller than the free-space optical solution. Ramachandran and his ...

Mar 19, 2024 Higher intensity x-ray beams don't always give stronger diffraction patterns (Nanowerk News) Turning up the intensity of x-ray beams used to probe the atomic structures of materials can ...

Turning up the intensity of x-ray beams used to probe the atomic structures of materials can actually reduce the intensity of x-rays scattered from the material, a RIKEN-led team has found. This ...
