World's Smallest Laser

Doing research for our nanobot project, I ran across this article about lasers. http://www.popularmechanics.com/science/extreme_machines/1280846.html I assume most of you won’t bother reading that, but basically it boils down to this. “Measuring barely a hundred-millionth of a millimeter across, the smallest nanolaser was crafted by Charles Lieber and his colleagues at Harvard University. It consists of individual wires of cadmium sulphide, a semiconductor similar to the silicon found in everyday electronic circuits.” The article goes on to say that these lasers can help surgeons perform microscopic surgeries. These lasers haven’t been perfected yet, because to draw power, they need to be activated by another larger laser, but these nanolasers have potential to destroy artery clogging plaque, but they also are trying to be used in devices outside of the biological realm, e.g. quantum computers. Another “problem” is that these lasers can only flash for about 100milliseconds before they lose power, but to destroy plaque, all we need is for our laser to turn on for a little bit, and zap the plaque, and turn off. For team Solo, this means the technology, as it stands now, is optimum for our specific nanobot. I think it’s fascinating that something so small can be developed that can help humans in such huge ways.
