Dictionary.com defines a laser as a device that produces a “…coherent beam of light [caused] by exciting atoms to a higher energy level and causing them to radiate their energy in phase”. So basically lasers are just beams of light created by some science-y means. Most of them aren’t weapons or even that harmful so long as kept away from the eyes. That dinky little laser pointer manufactured purely to annoy your pets counts as a laser. And of course they are often fairly small and thin, because a huge, wide laser would probably be ridiculously impractical, not to mention pointless. Lasers aren’t really weapons, there, now that’s out of the way. So that being said…fuck that shit!
Erm, not literally though. That probably wouldn’t end well, even if the laser itself wasn’t harmful.
