NEW PHENOMENON DISCOVERED THAT FIXES A COMMON PROBLEM IN LASERS: WAVELENGTH SPLITTING

投稿者:

A team led by University of Utah physicists has discovered how to fix a major problem that occurs in lasers made from a new type of material called quantum dots. The never-before-seen phenomenon will be important for an emerging field of photonics research, including one day making micro-chips that code information using light instead of electrons.

The study published on Feb. 4, 2019, in the journal Nature Communications.

Lasers are devices that amplify light, often producing a single, narrow beam of light. The strength of the beam depends on the material with which the laser was built; light passes through the material, which produces a beam made of light waves all with similar wavelengths, concentrating a lot of energy into a small area. This material property to be able to amplify the beam’s energy is called “gain.”
