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

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.
