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 ...

Integrated laser platform: A single chip generates narrow linewidth and tuneable visible light covering all colours. (Courtesy: Myles Marshall/Columbia Engineering) Researchers in the US have created ...

A pillar of light was spotted over a Russian town near the border with Ukraine, sparking theories it could be linked to a top-secret weapon.

Researchers at Columbia Engineering’s Lipson Nanophotonics Group have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the ...

A team of scientists has found that the narrow beam of a laser can cast a shadow — a surprisingly counterintuitive finding.

How Do Lasers Work in Dentistry? All lasers work by delivering energy in the form of light. When used for surgical and dental procedures, the laser acts as a cutting instrument or a vaporizer of ...

The Laser on My Mouse Doesn't Light. Whether the problem occurs sporadically or perpetually, a failing computer mouse always decreases productivity.

Recovery time for this type of therapy can be up to two weeks. Fractional laser therapy. Fractional therapy uses many narrow columns of light, causing the collagen in the scar to tighten.

In a significant advance for impactful technologies such as quantum optics and laser displays for AR/VR, researchers have invented the first tunable and narrow linewidth chip-scale lasers for visible ...
