Welcome to a new feature we're trying out over the next few weeks: the Manufacturing.net Video of the Day. With an increasing amount of good content being distributed through video, we feel that it's important to give space to the best ones we've found. And we all know that sometimes, it's good to just take a break and take in some cool sights or interesting ideas.
This video from Minute Physics gives a very basic introduction as to how lasers work, which is useful, since they seem to be the result of some incredibly complex physics. All in all, it's a tale of excited atoms, photons falling in love, and the creation of the actual usable beam. Pretty neat stuff.
