Light Amplification by Stimulated Emission of Radiation
Yep, that's right, laser is an acronym, like many other things that sound super cool to say, like NASA or DEFCON or SyFy. And it's super old. 50 years old to be exact. Though the first working laser performed successfully in May of 1960, 2010 is the the year of the laser. Just check out LaserFest 2010 if you need to get your geek on. If it weren't for lasers we wouldn't have the CD's that we never listen to or the DVD's that are about to become obsolete. We wouldn't have an even more tripped out way to experience Floyd or a way to make U2 tolerable. We wouldn't have gotten to hear Dr. Evil say,"You know, I have one simple request. And that is to have sharks with frickin' laser beams attached to their heads!" Terrible movie, great quote. Then there's this guy who built a working Phaser, but I think it can only be set to balloon stun, thankfully. Check out the dude's video here.
