LASER stands for Light Amplification by Stimulated Emission of Radiation and is an electromagnetic device that emits coherent light. Developed in 1960 by Theodore H. Maiman, lasers operate by reflecting waves within a cavity to produce a coherent output. The full form of LASER is Light Amplification by Stimulated Emission of Radiation . The term LASER describes a device that emits a concentrated beam of light with unique properties, making it important in fields like physics, medicine, engineering, and technology. LASER Full Form Lasers have become an integral part of our modern world, finding applications in various fields, from medicine and communications to A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
