"Nobody had engineered a way to control the emission of light from an LED into a single direction."

Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.

A new method could pave the way for shrinking particle accelerators from the length of Rhode Island to the length of a dining room table.

A new method can turn any metal surface into an antimicrobial material by changing its texture with lasers, researchers report.

"Our optical tweezer method lets us take the little machines out of the cell, gently hold onto them, and watch them go."

A new approach (and a smaller laser) lets scientists shrink laser-induced graphene for flexible electronics.

Currently, no one test can diagnose concussion. Researchers say a new device that uses infrared lasers could offer the first step in changing that.

Researchers have used femto-second laser pulses to etch nano-sized designs onto black metal, turning it into a solar energy absorber.
