New Nano-Laser Created 84

Many sources are reporting that researchers have created the world's smallest laser since the inception of lasers almost a half-century ago. Dubbed "spasers," as an acronym for "surface plasmon amplification by stimulated emission of radiation," their incredibly tiny size could become a critical component for future technologies like "nanophotonic" circuitry. "Such circuits will require a laser-light source, but current lasers can't be made small enough to integrate them into electronic chips. Now researchers have overcome this obstacle, harnessing clouds of electrons called 'surface plasmons,' instead of the photons that make up light, to create the tiny spasers."

      Enter the following in the console:

      apt-get sharkswithfreakinglasers
      make laser
      sudo intalllaser

      At this point you will get a number of incomprehensible error messages.

  • I see about three revolutionary breakthroughs per day, three of which never go anywhere because of cost or something. This reminds me of those "water on mars," articles -- we've been "getting new compelling evidence for water on mars" for decades. So, really, I've started to lose interest. I'll be excited when it finally goes somewhere. Really, what gets my blood pumping is what I can see coming down the pipe -- 128gb flash drives, C++0xA, etc.
    • So you see

      three revolutionary breakthroughs per day

      However

      three of which never go anywhere

      That'd be none then, zero, zilch, nowt, nothing.

        refinement of existing tech...

        and i think the problem of cost has more to do with not finding a process that can be applied to a henry ford style mass production, then something that can be made for profit (anything can be sold for profit, if the customer is willing to pay the price).

        that, and refinements of existing mass production processes outstrip the potential benefit of the new products, before things can be scaled up...

      • That'd be none then, zero, zilch, nowt, nothing.

        I know, that was the point. "Three out of three never go anywhere..." Of course, there are those rare breakthroughs that actually do something. Sure, it's nice to see Scientific tinkering, but I'm really most interested in stuff that is practical.

          You will never get practical stuff without "Scientific tinkering" (others call it "Research"). So if you're not interested in tinkering, simply skip articles like this one.
    • Well, believe it or not, there are some people who are interested in the "R" part of R&D as well as the "D" part.

          And without the "R," the "D" has nothing to do.

          The kind of thing TFA is talking about is a lot more than "just a nice thought." The researchers have done some very difficult, impressive work. Will it ultimately become a usable product? We have no way of knowing. But they've contributed to the sum of human knowledge in a meaningful way. This is pretty much how the relationship between science and technology works.

              Thanks. And yeah, I was thinking that when I made the original post.

              There does seem to be a contingent on Slashdot that sees science as kind of irrelevant. Scientists are ivory-tower eggheads with their heads in the clouds who waste their time on airy-fairy ideas, engineers are tough gritty workin' men with dirt under their fingernails who really make things happen ... that kind of thing. It's bullshit, of course, but it's very appealing bullshit to people who don't actually know that much about how science or engineering actually works, but think they do.

            And without the "D" producing a product that sells, there is rarely money for "R". Unfortunately it is not the academic minded handing out the research grants, it is the bean counters. (Otherwise all of our world problems would be likely solved by now.) This is pretty much how the relationship between science and reality works.

              Except here we have researchers at Purdue, a university with a history of a particularly strong and fruitful connection between science and engineering, doing solid scientific research which may well (or may not, of course) lead to useful commercial development. Believe me, I agree with you entirely about the "bean counters," and I would very much like to see more money directed toward pure research. (Part of this is pure self-interest, since I'm an academic scientist, but I felt this way back when I was doing corporate DBA work too.) The point is that while it may not happen enough, it does happen ... and "who cares" attitudes, like the one displayed in the OP which I replied to, are a major obstacle to it happening more.

    • I see about three revolutionary breakthroughs per day, three of which never go anywhere because of cost or something.

      You're saying that no fundamental breakthroughs ever "go anywhere", which is patently false. The amazing array of technology around us (from computers to MRIs to satellites to medical drugs) can be traced back to fundamental research breakthroughs.

      I will grant you that the majority of breakthroughs do not directly translate into a particular product. But that's the nature of research: we have to study a wide-variety of things to find those that are really significant for technology. Moreover just by push
