Abstract

Lasers, highly focused beams of energy, have been a standard in movies and games for many years. The word “laser” is an acronym that stands for Light Amplification by Stimulated Emiss of Radiation. Don’t worry what “Stimulated Emission” means right now. We’ll go over that la in this chapter. One of the reasons that lasers can be powerful is that they concentrate light or other types of radiation into a narrow, concentrated beam. A laser beam can burn through the skin of an airplane, disable electronic devices, blind enemy soldiers, and lots of other things besides.
