co-recipient of the 2014 Nobel Prize in Physics for the invention of blue light-emitting diodes, founded Blue Laser Fusion in Palo Alto, California, in November. Partners include Hiroaki Ohta ...

After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, ...

Blue lasers, lasers that emit a light beam with a wavelength between 400 nm and 500 nm, are key components of various ...

In a new study, researchers at Osaka University have created the world's first compact, tunable-wavelength blue semiconductor ...

Can light cast a shadow? It sounds like a tricky riddle, but researchers have shown that, under special conditions, a laser ...

Can light itself, perhaps from a laser, cast a shadow? It might seem like a trick question, but the answer to this is "yes." ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat ...

Researchers have made a significant breakthrough by observing how light can block other light, creating a visible shadow.

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 ...

A semiconductor laser that emits light in the 400-450 nm range. Although it was very difficult developing blue lasers, which emit smaller wavelengths than other colors, blue lasers became ...

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 ...
