Synopsis
It’s been fifty-some years since the laser was invented. They are now so common, most of us use them several times a day, but how do they work and what are some of the things we accomplish with them? We’ll go over a little of the physics of “stimulated emission” and explore ways we use lasers for entertainment, science, manufacturing, communications, and even surveillance. CAUTION: Do Not Look Into Laser With Remaining Eye.
