    Fricken' lasers!

    But seriously, this has been around for awhile though they call it something different. In the fiber optic world it is called over-the-air optical data transmission. Since fiber uses laser to transmit the light, they are already doing laser transmission with the OTA optical data transmission. Granted, they are doing point to point in a stationary environment, but it does occur. #lasernetworking

    @jmurph05:

    ... it fucks with the plane carrying the laser as well as distorts the light by being of various densities and having different levels of particulate matter suspended in it.

    lasers aren't perhaps as tightly coherant as people think of them being, even in vacuum. my 30mw green laser will expand to a baseball size dot at 1 mile. that's pretty significant diffraction. #lasernetworking

    @nutbastard: That's divergence, not diffraction. If you have a cheap laser, it's going to have a bad divergence, unless you manually focus it. A laser is still a laser, even if it has a huge divergence, like a flashlight.
    I'm sure they have a system to adjust the focus reasonably, but I wouldn't think it matters that much. Also, I assume they're using a very wide beam so particles don't get in the way as easily.

    @nutbastard: That sounds problamatic. Why not use something else that travels just as fast as light but wouldn't be easily affected by the medium. I know. Instead of laser, why don't they just use modulated waves of electromagnetic radiation at lower frequencies.

    diffusion was the word i was looking for in the instance of it being used in atmosphere. but yes, divergence is the proper term when describing the coherence of a laser. good on ya. #lasernetworking

    Here's what I got out of this article: A picture of an airplane and a headline that includes the word "laser". Therefore, I'm going to lazily assume this article is about planes made out of laser beams.

    Pew pew!

    Wow, it's almost like the smoke alarms in my hallway. To test or silence them, you take a flashlight and wave the beam over the detector. #lasernetworking

    @jakebathman: Not really. You have to wave it like 5-7 times quickly for it to do it. I think it's meant for houses with very tall ceilings that can't be reached easily.

    I know of some detectors that can be silenced with any IR remote. #lasernetworking

    So the big upshot of this new technology is that signals are more faithfully delivered while on the move. It seems like the encryption is sort of a fringe benefit, since I doubt anybody's out on the battlefield (in Iraq/Afghanistan, at least) trying to hack into our communication lines and send orders to our drones on the battlefield. #lasernetworking

    @Gordonium: Someone correct me on this, but wouldn't you have to literally put something directly between sending/receiving lasers, capture the signal (somehow) and retransmit it? Pretty tough to intercept if the sending and receiving units are both flying around #lasernetworking
