Laser Laser A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light "coherently". Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial
Living Laser he was poised to take over the world due to his possession of the Serpent Crown, but is foiled by the Avengers. At one point it appeared that the Living Laser exploded in space, but in reality his body was transformed into photon form, making him an actual living laser. The Living Laser debuted in "The Avengers" #34 (Nov. 1966) as Arthur Parks, a scientist who created wrist-mounted laser units and a costume (writer Mike Conroy stated "Arthur Parks was a scientist sufficiently proficient to design laser projectors small enough to wear on his wrists, quite the achievement in 1966.")
