Laser - an overview | ScienceDirect Topics
“LASER” stands for “Light Amplification by Stimulated Emission of Radiation.”2 It has an energy source (light or electric) and medium (liquid, gas, or solid).
Lasers operate based on the principles of stimulated emission and the properties of photons. Photons are packets of electromagnetic energy that make up light.
