What is Light Amplification by Stimulated Emission of Radiation?
Light Amplification by Stimulated Emission of Radiation, commonly known as LASER, is a process that generates a coherent beam of light through the mechanism of stimulated emission. In this process, an external energy source excites electrons in atoms or molecules to higher energy levels, and when these electrons return to their ground state, they emit photons. These photons stimulate other excited electrons to emit additional photons, creating a cascade of light amplification.
