The Laser Revolution

Lasers, an acronym for "Light Amplification by Stimulated Emission of Radiation," are devices that emit coherent light through a process of optical amplification. They operate on the principle of stimulated emission, where photons stimulate the emission of additional photons, resulting in a highly focused and intense beam of light. As technology advances, new types of lasers continue to emerge, including semiconductor lasers, fiber lasers, and solid-state lasers, each with unique benefits and applications. The ongoing research and development in this field promise to unlock even more innovative uses for lasers in the future.
