Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest ...

Until fairly recently, if you wanted to get a projector close to the wall or screen, the ultra-short-throw model you'd need ...

Researchers have developed a device that can precisely control laser light using a fraction of the power and space required today. Because it can be manufactured just like modern microchips, this tiny ...

Researchers at the University of Sydney have cracked a long-standing problem in microchip-scale lasers by carving tiny "speed ...

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 ...

'Laser' is an acronym for 'light amplification by the stimulation emission of radiation'. Its theoretical basis was postulated by Albert Einstein. The first tooth exposed to laser light was in 1960.

A laser measurer can help you take more accurate measurements at longer distances. Our favorite model has a handy feature that makes it ideal for use anywhere.

Whether the problem occurs sporadically or perpetually, a failing computer mouse always decreases productivity. In the early days of personal computing, mice had balls that sensed motion. Today's mice ...

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 ...
