What does LASER stand for?

Laser stands for Light Amplification by Stimulated Emission of Radiation. It describes the process that takes place within a laser device where a concentrated beam of light is generated. This is accomplished by stimulating atoms or molecules to emit photons of light in a specific direction, resulting in the amplification and coherence of the light waves. The emitted light is then further amplified and reflected between mirrors to produce a powerful, coherent and intense beam of light with specific properties like narrow wavelength and high precision. This acronym encompassing the key principles of the laser technology succinctly captures its functionality and operation.
