  1. Speckle? on A Widescreen Laser Projector In Your Pocket · · Score: 1

    Laser light seems wrong for this type of application. Images produced by laser light inevitably suffer from speckle (speckle is one of the hallmarks of laser light). I'd think having speckle patterns overlaying everything would make the images very annoying to watch, and probably degrade the resolution as well. Maybe they've dealt with this? Though that's hard to believe. Wouldn't they be better off with LEDs?

  2. It's what they don't say on The Texas Petawatt Laser · · Score: 3, Informative

    You have to put this in perspective. They may have made a laser with highest peak intensities but it's nowhere near the most energetic laser out there. According to their press release their pulses have 150 J of energy. Compare this to the National Ignition Facility at Lawrence Livermore laser, which will produce 1.8 MJ per shot when it is completed next year, or to the laser at the University of Rochester, which will produce several kJ. Though not yet finished, both these lasers have already demonstrated many kJ of energies.
