\nThe term LASER is an acronym for Light Amplification by Stimulated Emission of Radiation.
\n<\/section>\n
\nLASER is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The full form reflects the fundamental principle behind its operation.
\n<\/section>\n
\nThe first working laser was demonstrated in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow, building on the principles established by Albert Einstein regarding stimulated emission.
