| YOKOHAMA, Japan, June 21 (UPI) --
Japanese scientists have developed a highly efficient,
room-temperature nanolaser that produces stable, continuous
streams of near-infrared laser light.

MONEY ON TRAVEL DEALS
Yokohama National University researcher Toshihiko Baba and
colleagues said the overall device has a width of several
microns, while the part of the device that actually produces
laser light has dimensions at the nanometer scale in all
directions.
The laser uses only 1 microwatt of power, achieving one of
the smallest operating powers ever reported.
The researchers said their nanolaser design should be
useful in miniaturized circuits containing optical
devices.
The research appears in the journal Optics Express. - -
