How laser beams work

Web9 jan. 2024 · A laser is a device which is built on the principles of quantum mechanics to create a beam of light where all of the photons are in a coherent state — usually with the same frequency and phase. (Most light sources emit incoherent light, where the phase varies randomly.) WebA laser is created when electrons in the atoms in optical materials like glass, crystal, or gas absorb the energy from an electrical current or a light. That extra energy “excites” the …
