A laser is an optical device that produces laser light. A laser is a special type of light that is highly directional, monochromatic and coherent. The basic principle of operation of a laser involves exciting an atom or molecule, placing it in an excited state, and then releasing a photon through a process of excited radiation to produce a beam of coherent light.
