Ultrashort laser pulses—that are shorter than a millionth of a millionth of a second—have transformed fundamental science, ...

The SACLA free-electron laser facility, where the experiment on the diffraction of ultra-short X-ray pulses on crystalline silicon samples was carried out. When we illuminate something, we usually ...

For more than a century, X-Ray diffraction has been used to understand the structure of crystals or proteins; for example, the well-known double helix structure of DNA, which carries genetic ...

Medvedev modeled wave diffraction off a circular reflecting region with radially varying index of refraction outside of it to better understand the Crab Nebula’s zebra pattern. LAWRENCE — A ...
