# Laser Light Amplification by Stimulated Emission of Radiation — a device that emits coherent light through optical amplification. The theoretical foundations and early development occurred at [[wiki/Bell Labs|Bell Labs]], contributing to Charles Townes' 1964 [[wiki/Nobel Prize|Nobel Prize]] in Physics. Lasers became essential to telecommunications (fiber optics), medicine, manufacturing, and scientific instrumentation. Bell Labs' laser work is cataloged in [[articles/Bell Labs and the Distributed Architecture of American Power|Bell Labs and the Distributed Architecture of American Power]].
