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
Laser tag higher output power and specially designed optics are often a requirement. The units themselves are normally constructed of machined aluminum or a poly-carbonated plastic to withstand the abuse the outdoors brings. Players usually wear lightweight head sensors to receive hits. Operators typically either run games like indoor laser tag where you count the number of times you tag other players, or scenarios often approximate real-world combat, or a laser tag version of paintball games. Many paintball fields are adding laser tag to attract and groom players who are too young to play paintball. Some theme parks are adding outdoor laser
