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 ...

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

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 ...

The solid-state light-emitting diode (LED) is a key component of today’s semiconductor industry 1. The successful development of LEDs has enabled plenty of applications such as high-performance ...

Scientists at Japan's Institute for Molecular Science have achieved a 1,000-fold enhancement in white-light generation inside ...

SAN DIEGO (CBS 8) - Laser holiday lights are the new big thing in outdoor decorations this year, but law enforcement officials are warning that laser light shows can be dangerous. According to the FAA ...

When a high-energy laser hits certain substances, their atoms are ionized and heated into a plasma in a process known as laser-induced breakdown. After the laser is switched off, the electrons and ...

Blackmore's lidar system can detect the velocity of pedestrians and vehicles: objects moving away from the vehicle are in yellow or red, those moving toward it appear blue. This morning I got a ...

NEW YORK (CBSNewYork) --Block after block in Howard Beach, homes can go from drab to dazzling with just the flip of a switch. Many residents are taking an extra step this holiday season, by turning ...
