| Single nanomaterial yields many laser colors Posted: 29 Apr 2012 12:22 PM PDT Engineers have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots are made the same way of the same elements. In experiments, light amplification required much less power than previous attempts at the technology. The team's prototypes are the first lasers of their kind.  |
