University of California, Berkeley, astronomers have taken advantage of a recently mounted laser guide star system at UC’s Lick Observatory to obtain sharp, twinkle-free images of the faint dusty ...

The laser module is one of the least reliable components in such a system. For that reason, it remains in a convenient pluggable form, enabling easy and inexpensive replacement. If designers were to ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...

SHANNON, CLARE, IRELAND, February 27, 2026 /EINPresswire.com/ -- Announcing a new publication from Opto-Electronic ...

Last March, Nvidia debuted two data center switch families that use an emerging packet transmission technology called co-packaged optics, or CPO. Lumentum and Coherent both make laser components for ...

By harnessing two natural timescales in resonator arrays, researchers created photonic chips that reliably produce multiple harmonics without active compensation. For decades, scientists and engineers ...

As optical bandwidth requirements increase, system designers are turning to “coherent” modulation schemes that can place more data on the same laser light, and lower power over long connections. A ...

The optical industry “almost completely relies on mechanical processes in its process chains,” So says laser and photonics research center Fraunhofer Institute for Laser Technology (ILT). This, ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Shadows have been integral to humanity’s exploration of light and its properties. From their depiction in ancient shadow puppetry to their role in groundbreaking scientific discoveries, shadows have ...
