New Nano-Laser Created

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."

    So do they split into three parallel beams, thus covering a wider area than a single beam could along? And do they do the whole sinusoidal-oscillation thing if combined with a Wave Beam?

      Bah, this existed back in 1994. Problem is, it was mostly useless because you couldn't combine it with a Plasma Beam.

    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.

      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.

      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.
