A laser (Light Amplification by Stimulated Emission of Radiation) is a device that produces a concentrated beam of coherent light by amplifying light through stimulated emission. The process involves exciting a gain medium, such as a gas, crystal, or fiber, which releases photons that interact with other excited atoms or molecules, leading to a cascade of stimulated emission.
