In the realm of beauty tech, red light therapy reigns supreme. However, at-home laser treatments have been quietly gaining ...

Researchers have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast -- up to ...

A simple burst of visible light can now create skin-safe electrodes that could transform medical and wearable electronics.

Researchers in Sweden have unveiled a way to create high-performance electronic electrodes using nothing more than visible light and specially designed water-soluble monomers. This gentle, ...

WASHINGTON — Researchers have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...

Researchers in Quebec, Canda, have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...

Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials. Now scientists from McGill University, Montreal, Canada, have developed what they are calling ...
