Who Wants a Laser Gun?

Science Fiction is now reality:
G.I. Joe used them to battle Cobra’s evil forces. Han solo shot his first in the Mos Eisley Cantina. For years, hand-held pulse laser guns have been something that existed only in the realm of cartoons and movies…until now.

German hacker [Patrick Priebe] recently constructed a laser pulse gun that looks so good, it could have easily come off a Hollywood movie set. Its sleek white and black exterior adds intrigue, but offers little warning as to how powerful the gun actually is.

He says that the pulse power is 1 megawatt (that's 1 million watts). He doesn't say if it's Q-switched or not, which would determine whether the pulses are long or short. I suspect that they are short, tens of nanoseconds and therefore with tens of millijoules of energy per pulse. On the other hand, it does seem a bit compact to be a Q-switched laser. As for what would happen if you shot someone with it (NOT THE EYES!), it would hurt a little to be shot by that if the lens is removed and the laser is not focused, and it would would leave a small but painful burn if focused.
