    how expensive would a laser guna cost? theres suffient strong enough lasers in labs to be used as guns or like ive heard on the front of stealth planes and the euro fighter etc to take down incoming missiles or from above take out specific people in a crowd instead of drone bombing a whole area where terrorists are with there families and human shieilds with a drone low enough down to use as a camera soource you could easily pin point one person as if you were in a helicopter shooting with a mounted gun it would would be pin point and would not miss!! i know it would be exceptionally expensive to mount these on guns and have a a computer wired into the guna but say for a sniper it would be perfect. it would be a defanate kill as it would be instant and in a ray beam so it would not miss and travel at light speed dont they so i thought so there is less cvhance of by standers being hurt

    I'm guessing you just saw the 1985 movie "Real Genius"? Great flick! If you haven't seen it, you should really check it out. As for cost, the laser you are proposing would cost exactly $21,472,921.43 plus two photos of your sister naked.

    Seriously though...one problem you have with shooting high power lasers through long distances of air is called "blooming". Once the power density of the beam reaches a certain point, it will actually heat up the air it's passing through enough to cause it distort, which in turn de-focuses the beam. Another problem is a power source....current laser are really inefficient, so powering them and making them portable is big obstacle.

    Makes me kind of sad how much America loves to weaponize everything.

    MacGyver1968 gave you a great answer. The US and others have been working on "directed energy" weapons for a good long time. There's a reason you haven't seen them deployed. A book called "Imaginary Weapons" gives a pretty good accounting, although it's a bit sloppily written (a good editor would have fixed the spelling and grammar mistakes that pervade the book).That said, the Israelis have a laser cannon. Under certain conditions, it even works.

    Problems there:

    1) A visible or near-visible laser will blind anyone nearby the target. If there is dust/fog/rain/snow/haze in the air it might blind people near the marksman as well.
    2) The power source would need to be huge
    3) You would likely only get one or two shots off before you had to let the weapon cool
    4) Everyone will know exactly where the sniper is after the first shot
