Skyguard (area Defense System)
Skyguard is a chemical laser-based area defense system proposed by Northrop Grumman, to protect airports and other areas against a variety of military threats including short-range ballistic missiles, short- and long-range rockets, artillery shells, mortars, unmanned aerial vehicles and cruise missiles. Each shot costs about $1,000 which represents the cost of consumable chemicals. retrieved March 11, 2012 See also * Tactical High Energy Laser, a joint American-Israeli laser system for missile defense. * |
Chemical Laser
A chemical laser is a laser that obtains its energy from a chemical reaction. Chemical lasers can reach continuous wave output with power reaching to megawatt levels. They are used in industry for cutting and drilling. Common examples of chemical lasers are the chemical oxygen iodine laser (COIL), all gas-phase iodine laser (AGIL), and the hydrogen fluoride (HF) and deuterium fluoride (DF) lasers, all operating in the mid-infrared region. There is also a DF–CO2 laser (deuterium fluoride–carbon dioxide), which, like COIL, is a "transfer laser." The HF and DF lasers are unusual, in that there are several molecular energy transitions with sufficient energy to cross the threshold required for lasing. Since the molecules do not collide frequently enough to re-distribute the energy, several of these laser modes operate either simultaneously, or in extremely rapid succession, so that an HF or DF laser appears to operate simultaneously on several wavelengths unless a wavelen ...
