Laser weapon is a kind of directional energy weapon that directly damages or invalidates a target by using a targeted laser beam. According to the different operational uses, laser weapons can be divided into two categories: tactical laser weapons and strategic laser weapons. The weapon system is mainly composed of lasers and tracking, sighting, and launching devices. At present, lasers commonly used include chemical lasers, solid lasers, and CO2 lasers. Laser weapons have the advantages of fast attack speed, flexible steering, precision strike, and protection from electromagnetic interference, but they also have vulnerabilities such as weather and environment. Laser weapons have been developed for more than 30 years, and their key technologies have made breakthroughs. The United States, Russia, France, Israel and other countries have successfully conducted various laser target tests. At present, low-energy laser weapons have been put into use. They are mainly used for jamming and blinding optical sensors at relatively close range, as well as attacking human eyes and some enhanced observation equipment; High-energy laser weapons mainly use chemical lasers. According to the current level, they are expected to be deployed on ground and air platforms for tactical air defense, theater anti-missile defense, and anti-satellite operations within the next 5-10 years. Laser weapons are characterized by highly clustered lasers and are also very concentrated in energy. For example; In everyday life, we think that the sun is very bright, but a giant pulse red Gemstone laser emits a laser that is 20 billion times brighter than the sun. Of course, the laser is brighter than the sun, not because its total energy is larger than the sun, but because its energy is very concentrated. For example, a laser beam emitted by a Ruby laser can penetrate a 1/3 cm thick steel plate, but the total energy is not enough to cook an egg. Laser as a weapon has many unique advantages.
