Designing lasers based on quantum physics
(PHYSorg.com Physics)

A five-country research team coordinated by Germán J. de Valcárcel Gonzalvo, Professor of Optics at the University of Valencia, has developed a new theory -the coherent master equation- that describes the behavior of pulsed lasers based on fast materials and highlights its effects of quantum coherence (the ability of material and light electrons to oscillate in unison for some time). These lasers can emit intense pulses of light of one billionth of a second at a constant rate and have great technological and scientific impact.
