Laser Weapons high energy laser weapon The use of high-energy laser beam directed energy weapon to destroy aircraft, missiles, or other targets Sputnik makes failure. Also known as high-energy laser weapons, light artillery. It mainly consists of high-energy lasers, precision targeting and tracking systems transmit beam control systems and system components. High-energy laser is the core of a strong laser weapon, used to produce high-energy laser beam. U.S. high-energy laser average power requirement of at least 20,000 watts or pulse energy of 30 000 joules or more. National studies concerning energy lasers, carbon dioxide lasers, chemical lasers, excimer lasers, free electron lasers, nuclear excitation lasers, X-ray lasers and γ-ray lasers. Precision targeting tracking system for capturing, tracking target, target shooting guide beam and determine damage effect. Laser weapons are a direct hit by a laser beam targets and stay a certain time and cause damage, so aim to track the speed and high precision. Laser weapons are strong advantages: a laser beam to the speed of light, when shooting generally do not consider the amount in advance, high hit rate; laser beam quality is close to zero, almost no recoil, can quickly transform shoot direction, intercepting and more in a short time goals. Its weaknesses are: laser beam divergence angle range increases with increased power density of the laser beam incident on the target also decrease damage weakened, so that the effective distance is limited. Use subject to environmental impact. Laser weapons are not only to intercept low-altitude fast-moving aircraft and tactical missiles, and anti strategic missiles, anti-satellite and optical confrontation combat, can play a unique role. But it does not replace other weapons, but needs conjunction with other weapons.

Also known as high-energy laser weapons or light artillery. It mainly consists of high-energy lasers, precision targeting and tracking systems and beam emission control system components. High-energy laser is the core of a strong laser weapon, used to produce high-energy laser beam. U.S. high-energy laser average power requirement of at least 20,000 watts or pulse energy of 30 000 joules or more. National studies concerning energy lasers, carbon dioxide, chemical, excimer, free electrons, nuclear excitation, X-ray and γ-ray lasers. Precision targeting tracking system used to capture, track targets and guide the beam to aim and shoot, and determine the damage effect. Laser weapons are a direct hit by a laser beam targets and stay a certain time and cause damage, so aim to track the speed and high precision. Has been developed with infrared, laser radar and other TV and high-precision optical aiming tracking devices. Emitting light flux control system and the laser beam is focused onto the target quickly, and to achieve the best effect of destruction. Its main component is a high reflectivity, a large mirror-resistant high-powered laser radiation. Has been developed with a diameter of four meters or more mirrors, and actively develop adaptive optics system to overcome the atmospheric effects. Laser weapons are strong advantages: a laser beam to the speed of light, when shooting generally do not consider the amount in advance, high hit rate; laser beam quality is close to zero, almost no recoil, can quickly transform shoot direction, intercepting and more in a short time goals. Its weaknesses are: laser beam divergence angle range increases with increased power density of the laser beam incident on the target also decrease damage weakened, so that the effective distance is limited. Use subject to environmental impact. If the atmosphere will dissipate energy of the laser beam, and make it happen jitter, extensions and off_set_s. Inclement weather (rain, snow, fog, etc.) and battlefield smoke, artificial smokescreen for its greater impact. Laser weapon intercept low-altitude aircraft and tactical missiles fast, anti strategic missiles, anti-satellite and optical confrontation, can play a unique role. But it does not replace other weapons, but needs conjunction with other weapons. Laser weapons research began in the early 1960s. Countries to carry out research in this area are mainly the United States, Soviet Union, France, Germany and other federal United States, the Soviet Union and China into force max. Strong technical problems developing laser weapons have to be addressed: the development of the excellent performance of high-energy lasers; development of high-precision tracking system targeting; mechanism of laser damage to the target and overcome atmospheric effects; development of large mirrors and adaptive optics systems, and engineering assembly and equipped automated command, control, communications systems and other issues. The United States has been very strong emphasis on laser weapons, actively develop various cell technology, and developed a number of experimental prototype, conducted demonstration of validation tests. For example, in 1978, with a deuterium fluoride chemical laser to shoot down some "Tao" anti-tank missiles; 1979, with laser irradiation simulated ICBM boosters, deform, fracture; May 1983, with the machine containing carbon dioxide laser to shoot down five "Sidewinder" air to air missiles, September and shot down three simulated attack low-flying cruise missiles, warships drone. In the Soviet Union for the development of high power laser weapons research expenses of about 3 to 5 times the United States, roughly the same level of development and the United States.
