Laser science awarded the Nobel Prize in Physics in 2018 for groundbreaking inventions in the field of laser physics. The first working laser (a pulsed ruby laser) was demonstrated on May 16, 1960, by Theodore Maiman at the Hughes Research Laboratories. Laser science Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal evolution of the light field in the laser. It is also concerned with the physics
Laser tag tag facilities. Competitions and tournaments are staged for local, regional/state, inter-regional, national, bi-lateral international, and international levels. The First Zone Worlds Laser Tag Championships were hosted in the United States. Ultrazone's San Diego site in California hosted Worlds I from 2–7 August 2003. Worlds I featured 12 teams from Sweden, Finland, Canada and the United States. The tournament was played on v5 equipment and took place between 11pm to 6am. Results: The Second Zone World Laser Tag Championships were staged at Megazone in Tampere, Finland during 30 May – 4 June 2009, with teams including Australia, Sweden, U.S., and the
