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 ...

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 ...

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 ...

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, ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

What prompted the MIT team to research and develop a nanoscale "flashlight"? Details on the metasurface that was designed to create the source-beam collimator. How a DNN, CNN, and machine learning ...

(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 ...

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 ...
