Laser pointer weapons, let’s take a look. Let me briefly review that laser weapons use its monochromaticity, coherence, directionality, and high energy density. In fact, lasers are widely used in our various services and arms. Laser weapons have many characteristics. They have better maneuverability, high flexibility, where to hit, high hit rate, immunity to electromagnetic waves, and it is much cheaper than conventional missiles. "Patriot" missiles cost 300 to 500,000 U.S. dollars each, and "Stinger" air defense missiles cost 20,000 U.S. dollars each. Today's all-solid-state lasers are about one dollar for a pulsed laser. These are individual weapons and traditional guns, with lasers installed in them. This is an Israeli turning rifle. It is equipped with a laser sighting device, which can turn the laser barrel to aim and shoot at any corner. This is our domestic turning rifle. This is the tank, the American M1A2 main battle tank (Figure 19), a weapon that was used extensively by the US military in the Middle East war. It was equipped with advanced laser detectors, laser rangefinders, and so on. This is China's main battle tank. This tank is mainly for export and has a laser rangefinder installed in it. The US "Nightingale" fighter (Figure 20) is equipped with laser-guided bombs. Our Chinese Xiaolong fighter is also equipped with laser weapons.
