Light Amplification by Stimulated Emission of Radiation

Light Amplification by Stimulated Emission of Radiation (LASER) is a process where atoms or molecules are energized to emit light coherently. When energized, they release photons that stimulate other excited atoms to emit identical photons, creating a focused, intense, and coherent beam of light. This process amplifies the light while maintaining its direction, wavelength, and phase. LASER technology is used in various fields such as medicine, communications, and manufacturing due to its precision and strength. Essentially, a laser produces a highly concentrated beam of light through controlled stimulated emission of photons.
