Disposable Lasers Created Using Inkjet Printer (dailymail.co.uk) 60

An anonymous reader quotes this report from The Daily Mail: Researchers have invented a way to print lasers that's so cheap, easy and efficient they believe the core of the laser could be disposed of after each use. The disposable organic lasers amplify light with carbon-containing materials and they are produced using a simple inkjet printer...

"The low-cost and easiness of laser chip fabrication are the most significant aspects of our results," said Sebastien Sanaur, an associate professor in the Center of Microelectronics in Provence at the Ecole Nationale Superieure des Mines de Saint-Etienne in France... One obstacle that has held back organic lasers is the fact that they degrade relatively quickly -- but that hurdle might be less daunting if the lasers are so cheap they could be tossed when they fail. Sanaur's research team produced their ultra-low-cost organic laser using a familiar technology: an inkjet printer... They estimate it could be produced for only a few cents. Like the replaceable blades in a razor, the lasing capsule could be easily swapped out when it deteriorates.

    Why the fuck would anyone create yet another disposable anything? Is there a widespread contagion of viruses caused by unsanitary lasers shared by groups of people?

    We live in a closed system with limited ressources, stop wasting them and turning them into garbage!

        Because it is destroying the world and bottom line man kind?

          Capitalism + technology is the best chance the world has, period (unless you're a fan of the Fallout way of life). Scary that people are starting to use their capitalism invented technology to berate the system.

        Not too long ago, fewer than 10 years ago, people here used to get excited about developments like this and all the new technologies it would enable. Print a monitor or any sort of electronic circuit on a piece of cheap paper for pennies, no more big polluting factories. Download and print a cell phone, print a wall size monitor. It's what all the nerds wanted.

        Now nerds want comic book movies and to complain about the doom and gloom of the future. Well good luck with that. The enlightenment is dead, long live romanticism. I hear there's a new zombie move coming out.

          To be fair, wages have stagnated [motherjones.com] and lots of people are out of a job [wordpress.com].

          It makes perfect sense [wikipedia.org] to be worried about the future, and devote time to complaining and looking for solutions.

      I'm just trying to figure out a use case for a disposable laser.

      The only one I can come up with is some kind of party favor and even then I'm guessing it would need a power source.

      It usually seems that any value beyond "ooh, laser" almost always requires some amount of non-disposable electronics that make the laser useful.

      Anything can be disposable at any price if the use has other constraints. I've worked with equipment in the past used for mining and ocean monitoring equipment that had $1k+ lasers that were disposable, because it would have taken a lot more resources to make the rest of the equipment survive longer or be easier to retrieve, etc. A classmate in grad school worked on an experiment that would destroy about $10k with of optics every time it went off. But that was enough years ago that now the experimental s

    • From the paper, the author's conclusions: In this paper, we show that inkjet printing can be successfully applied to external-cavity vertically emitting thin-film organic lasers and can be used to generate a diffraction-limited output beam with an output energy as high as 33.6J with a slope efficiency S of 34%. Laser emission shows to be continuously tunable from 570 to 670nm using an intracavity polymer-based Fabry-Perot etalon, and extension to the whole visible spectrum is straightforward with a proper

      Yes, it does. Lasers based on organic dyes are known for decades. I've seen a DIY project in 1970-s magazine. And it was large. Something like, yes, a gallon bucket. What is interesting in this new approach is that it is small.

    Do Not point LASER at remaining eye.

  • Cheap or done by inkjet printers? Make up your mind!

  • None of these words go together.
  • I guess I'm missing something cause for the life of me, I can't figure out what problem this is supposed to be solving. Apart from maybe healthcare (sterile laser "heads" for laser-based surgeries, etc), I don't see why someone would need single use disposable lasers.
