When cities transform into a colorful world of lights as darkness falls, it's often only possible to estimate their contours, which depending on the perspective can draw the attention to key details ...

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 ...

The ability of new blue-light semiconductor lasers to better perform precision cutting, patterning or welding of copper will make electrical and electronic component manufacturing cheaper and more ...

GOLETA, Calif.--(BUSINESS WIRE)--KYOCERA SLD Laser, Inc. (KSLD), a world leader in commercialization of laser light sources, is introducing its new high power 5 watt blue laser diode products for ...

In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

After a test run with confusingly coincidental origins, a massive blue laser will once again light up Grace Cathedral this month. Illuminate — the arts nonprofit that lit up the Bay Bridge — and the ...

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 ...
