Learning about Lasers
Roberts, Larry
Tech Directions, v70 n8 p29-36 Mar 2011
The word laser is an acronym. It stands for Light Amplification by Stimulated Emission of Radiation. Lasers, invented in 1958, are used to cut and fuse materials, accurately survey long distances, communicate across fiber-optic phone lines, produce 3D pictures, make special effects, help navigation, and read bar codes for cash registers. A laser produces a special form of light. In this article, the author provides a few basic facts about light. Four laser activities are appended.
