A laser emits photons. Photons (from Greek ÏÏÏ, meaning light), in many atomic models in physics, are particles which transmit light. In other words, light is carried over space by photons. Photon is an elementary particle that is its own antiparticle. In quantum mechanics each photon has a characteristic quantum of energy. Photons have a rest mass of 0 (zero).
