Lasers, an acronym for “Light Amplification by Stimulated Emission of Radiation,” are devices that emit highly focused beams of light. First developed in 1960, lasers function on the principle of stimulated emission, where electrons in atoms are excited to a higher energy level and then drop back to a lower level, releasing photons (light particles) in the process. These photons stimulate other electrons to emit more photons of the same phase, direction, and wavelength, producing a coherent, monochromatic beam of light. Lasers vary in type based on the medium used to amplify the light, including gas (like CO2 or helium-neon), solid-state (like ruby or neodymium-doped yttrium aluminum garnet), dye, and semiconductor materials.
