Because the law of thermal radiation state that materials that can absorb a great deal of energy will also emit large amounts of energy, the researchers decided to see if their laser treatment would ...

BMW's first laser headlamps feature three blue laser beams per headlamp. The i8's lasers are said to produce an exceptionally bright light, with BMW claiming much greater luminous intensity than ...

Initially this laser light system will only be used for the high beam. BMW claims that the new headlamps are smaller, more energy efficient and can illuminate the road up to 600 metres ahead of ...

Halogen bulbs used in automobiles typically emit a yellowish light and despite the technology being over 50 years old, it is widely used. In terms of brightness, halogen lamps have a throw of ...

Halogen light bulbs are fairly easy to replace and tend to output about 1000 hours of light before the globes expire and need to be swapped. Halogen bulb technology has been around for some time ...

"If a light bulb is a white light, it has all colors represented," Umstadter added. "A laser is typically one color, and it is a very narrow beam — it's what we call coherent.

PICATINNY ARSENAL, N.J. (June 21, 2012) -- Scientists and engineers at Picatinny Arsenal are busy developing a device that will shoot lightning bolts down laser beams to destroy its target ...

This unexpected source of laser-like light is not just an academic oddity. The new work shows that the coherent light coming from shocked salt should be in a fequency band called terahertz ...
