Quantum-Dot Nano-Lasers

TanMauWu writes "An article in the April 2001 issue of Technology Review reports the creation of "Nanodot Lasers". These lasers can potentially output coherent light in a very wide range of frequencies, as opposed to the limited frequencies modern lasers can provide."

The lasers are semiconductor particle quantum dots — just a few nanometers across — and quantum effects tune the color of the glow to the size of the particle. The work was conducted by MIT chemist Moungi Bawendi and Victor Klimov, a laser expert at Los Alamos National Lab in New Mexico.
