Dual-color lasers could lead to cheap and efficient LED lighting

(Phys.org) —A new semiconductor device capable of emitting two distinct colours has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally ...

Image: Hubble snaps speedy star jets

This striking image features a relatively rare celestial phenomenon known as a Herbig-Haro object. This particular object, named HH111, was imaged by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3).

Turning metal black more than just a novelty

(PhysOrg.com) -- University of Rochester optics professor Chunlei Guo made headlines in the past couple of years when he changed the color of everyday metals by scouring their surfaces with precise, high-intensity laser bursts.

Carbon nanotube device can detect colors of the rainbow

Researchers at Sandia National Laboratories have created the first carbon nanotube device that can detect the entire visible spectrum of light, a feat that could soon allow scientists to probe single molecule transformations, ...

NIST infrared frequency comb measures biological signatures

Researchers at the National Institute of Standards and Technology (NIST) and collaborators have demonstrated a compact frequency-comb apparatus that rapidly measures the entire infrared band of light to detect biological, ...
