When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

The gem 561 laser from Laser Quantum provides up to 1000 mW of yellow light in a near diffraction-limited TEM00 beam with an M²<1.2. The gem 561 can be easily integrated into OEM applications and has ...

The first high-resolution x-ray diffraction imaging of an aerogel, performed at beamline 9.0.1 of the Department of Energy's Advanced Light Source at Lawrence Berkeley National Laboratory, has ...

This calculated diffraction image shows how forked diffraction gratings shape the atoms' wave function into a vortex. (Courtesy: Science/AAAS) A wave-like property previously only seen in beams of ...

A fibre-based source of near-ideal Bessel beams will be crucial for applications that require remote beam delivery as well as diffraction-free propagation. Scientists at OFS Laboratories in Somerset, ...

Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...

Diffraction gratings could allow laser-sailing craft to hold the line. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Spacecraft could fly to ...

(Nanowerk News) While laser-based 3D printing techniques have revolutionized the production of metal parts by greatly expanding design complexity, the laser beams traditionally used in metal printing ...

Electron spiral: phase of the beam near the tip of the needle Twisted beams of electrons have been used for the first time to determine the handedness, or “chirality”, of an ultrathin crystal. The new ...
