The manufacturing principle and beam size of a large laser pointer

Large Laser pointer indicators are usually considered laser weapons. Laser weapons came from the cold war between the United States and the Soviet Union in the last century, and both sides have made some progress. However, in the field of laser weapons, the new Chinese player seems to have reached the peak and hardly took the lead. Laser weapons, although very good, are not advanced enough. When China and the United States secretly compete for laser weapons, India will also aim at this "dessert". High energy laser weapon is a new weapon concept, which attacks by high-energy beam. The ability to respond quickly to lightning wars, the precise ability to attack and fail in surgery, especially the ability to satellites and destroy the enemy's information systems, they have turned it into the main weapon of the next generation of wars and adapted to the high-tech wars of the 21st century. In order to attack the target, it depends on the laser generated by atomic level conversion. It has the virtues of speed, maneuverability, continuous shooting ability, destructive ability, light logistics support and so on. It has special military significance in the complex electromagnetic environment in the future.
