Nanocrystals amplify light
Abstract:
Physicists have found a new way to amplify light that could make lasers more efficient. Chris Phillips at Imperial College in London and colleagues at the University of Neuchâtel in Switzerland made the breakthrough using specially patterned nanocrystals that behave as artificial atoms. Because the separation between energy levels in their crystals can be controlled, laser light can be produced without the need for a population inversion. The technique could also find applications in optical data storage and even allow materials to become completely transparent.
