Beam-powered propulsion — is a class of spacecraft propulsion mechanisms that use energy beamed to the spacecraft from a remote power plant. Most designs are rocket engines where the energy is provided by the beam, and is used to superheat propellant that then provides… … Wikipedia
Laser propulsion — is a form of Beam powered propulsion where the energy source is a remote (usually ground based) laser system. This form of propulsion differs from a conventional chemical rocket where both energy and reaction mass come from the solid or liquid… … Wikipedia
laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; … Universalium
Laser turntable — A laser turntable is a phonograph that plays gramophone records using a laser beam as the pickup, rather than a conventional diamond tipped stylus. This playback system has the unique mechanical advantage of never physically touching the record… … Wikipedia
Laser hair removal — Epilation by laser was performed experimentally for about 20 years before it became commercially available in the mid 1990s. Intense Pulsed Light (IPL) epilators, though technically not a laser, use xenon flash lamps that emit full spectrum light … Wikipedia
Laser tag — is a team or individual sport where players attempt to score points by engaging targets, typically with a hand held infrared emitting targeting device. Infrared sensitive targets are commonly worn by each player and are sometimes integrated… … Wikipedia
Apache Point Observatory Lunar Laser-ranging Operation — APOLLO shooting a laser at the Moon. The laser pulse is reflected from the retroreflectors on the Moon (see below) and returned to the telescope. The round trip time tells the distance to the Moon to great accuracy. In this picture the Moon is… … Wikipedia
Raman laser — The Raman laser is a byproduct of Raman scattering, discovered in 1928 by Nobel laureate Chandrasekhara Venkata Raman and Kariamanickam Srinivasa Krishnan in liquids and independently by Grigory Landsberg and Leonid Mandelshtam in crystals. When… … Wikipedia
Nova (laser) — View down Nova s laser bay between two banks of beamlines. The blue boxes contain the amplifiers and their flashtube pumps , the tubes between the banks of amplifiers are the spatial filters. Nova was a high power laser built at the Lawrence… … Wikipedia
Nova laser — Nova was a high power laser built at the Lawrence Livermore National Laboratory (LLNL) in 1984 which conducted advanced inertial confinement fusion (ICF) experiments until its dismantling in 1999. Nova was the first ICF experiment built with the… … Wikipedia
