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).

    Lasers for my nano sharks.

    Sharks get all the cool gear.

    Or perhaps common viruses were feeling inferior for some reason, and needed to upgrade.

    If so, I blame Ebola. That bitch can be downright ruthless on the playground.

    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.

  4. 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"?

    Laser array memory? Internal chip communication? UV laser sterilization wrap? Just off the top of my head. I'm sure there's more.
