Nonlinear effects cause different parts of a wave to move at different velocities and distort the light's periodic sinusoidal pattern. These effects generate new wavelengths and result in what ...

In 1845, Michael Faraday showed that light and magnetism are linked. He passed a beam through glass inside a magnetic field ...

Over the past several decades, researchers have been making rapid progress in harnessing light to enable all sorts of ...

When an intense laser pulse hits an electron at rest, the latter performs a quiver motion with the frequency of the light ...

A flash of light hits a simple iron crystal. In the space of a trillionth of a second, its magnetic behavior shifts, as if the solid briefly becomes something else.

Researchers uncover how laser beams cause atomic motion in Janus semiconductors, advancing understanding of light–matter interaction for future optical and ...

Laser light can physically distort Janus TMD materials, revealing how their asymmetrical structure amplifies light-driven ...

PITTSBURGH (KDKA) - Pittsburgh has gained a national and international reputation for the medicine being practiced here. New developments continue to improve a patient's quality of life even as they ...

For decades, scientists have sought ways to compress the tools of optical science – lasers, lenses, mirrors – onto chips that fit on a fingertip. Such ...

Following as many as four Nd:YAG-laser vitreolysis procedures, mean IOP actually increased slightly from 14.2 to 15.3 mm Hg and the logMAR (minimum angle of resolution) declined from 0.14 at baseline ...
