Laser laser devices. The question of just how to assign credit for inventing the laser remains unresolved by historians. On May 16, 1960, Theodore H. Maiman operated the first functioning laser at Hughes Research Laboratories, Malibu, California, ahead of several research teams, including those of Townes, at Columbia University, Arthur Schawlow, at Bell Labs, and Gould, at the TRG (Technical Research Group) company. Maiman's functional laser used a solid-state flashlamp-pumped synthetic ruby crystal to produce red laser light, at 694 nanometers wavelength; however, the device only was capable of pulsed operation, because of its three-level pumping design scheme. Later that year,
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
