Researchers Create Working Nano Laser

Posted by Unknown on from the viruses-with-lasers-you-say dept.

Zothecula writes "Researchers at Northwestern University have developed a laser the size of a virus particle that can operate at room temperature. The 'nanolaser,' which uses gold nanoparticles instead of mirrors, is claimed to be the first demonstration to make use of a so-called bowtie arrangement of metal nanoparticles, though nano-scale lasers have been previously demonstrated." Original paper (paywalled, unfortunately).

    That's great. Seems to be wonderful. But what will it be used for / with ? What industry will benefit of this "invention" ?

    Funny, they asked the same things when lasers themselves were invented. Nowdays, how many lasers are in your house? The fact is, you never know when a "useless" invention or discovery will turn out to be earth-shaking.

  2. MIT does not have researchers? by Yokoshima · · Score: 3, Interesting

    Why is it that anytime MIT does something Slashdot reads "MIT does something" (see http://games.slashdot.org/story/12/11/07/1559210/mit-slows-down-speed-of-light-in-new-game) and whenever another university does something it is the generic "Researchers do stuff"?
