Metasurfaces offer an innovative approach to controlling light. Courtesy: P Genevet Vertical-cavity surface-emitting lasers (VCSELs) have emerged as a highly versatile light source over the past 30 ...
researchers at Colorado University Boulder have used doughnut-shaped beams of light to take detailed images of objects too tiny to view with traditional microscopes. The researchers say that the new ...
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 ...
CHEMNITZ & JENA, Germany--(BUSINESS WIRE)--Vistec Electron Beam GmbH, a leading supplier of electron-beam lithography systems, announced that Fraunhofer ENAS in Chemnitz has purchased a Variable ...
Needle-shaped laser beams (NBs) featuring a long and narrow localization of photons can potentially allow non-diffracting pulses with undistorted temporal profiles. Using this kind of pulse in ...
