What is the difference between a military laser pointer and a laser in a science fiction film?

The laser is invisible if it is there. Any green laser pointer is the same, because the characteristic of laser is that it will not spread out, that is, without light, it will run into our eyes, and naturally we will not be able to see it.

The laser is invisible if it is there. Any green laser pointer is the same, because the characteristic of laser is that it will not spread out, that is, without light, it will run into our eyes, and naturally we will not be able to see it. The beams of light we see are all scattered by dust. To put it simply, the laser has a wide range of wavelengths, from the invisible ultraviolet (deep violet, extremely violet), to the visible visible light, and to the invisible infrared (near, middle, and far infrared). The laser uses heat as a weapon to kill. Naturally, the most important thing to consider is the absorption rate of the material. The higher the absorption rate, the faster the heat accumulates in the material, and the easier it is to produce lethality. The invisible infrared band is more in line with the above requirements, so choose the invisible.

Laser technology is not the offensive weapons seen in games or videos. Laser technology is mostly used for guidance, communication, and detection. Examples are laser guidance equipment for guiding missiles, infrared communication equipment, and lasers for tanks. In the rangefinder, the distance of the laser in the environment that humans can touch is almost a straight line. The light attribute is incidental energy and has particle characteristics. As a result, light energy can be used as a medium of various information and can produce a certain amount of energy transmission.

The application of laser in the military

Laser destroying satellites can be carried out on the ground, in the air and in space. At present, the energy of a single high powered laser pointer cannot destroy a high-orbit satellite, but several lasers can be aimed at a satellite at the same time to attack and destroy it. Space laser anti-satellite is to install lasers on satellites or space shuttles to attack the other's satellites; aerial laser anti-satellites are to install lasers on airplanes to attack satellites. It can overcome many shortcomings of ground-launched lasers to attack satellites, but it is not as good as spacecraft. Attacking satellites is so ideal, because the spacecraft is more stable than an airplane, and there is no interference from air currents and flight vibrations, so the energy of the laser can be fully utilized.

Metal laser ranging technology. It is the first Burning Laser Pointers technology to be practically applied in the military. At the end of the 1960s, laser rangefinders began to be equipped with troops, and many types have been developed and produced. Most of them use yttrium aluminum garnet lasers with a range accuracy of about ±5 meters. Because it can quickly and accurately measure the target distance, it is widely used in reconnaissance measurement and weapon fire control systems.

Laser guidance technology for metal second-hand Rechargeable Laser Pointer cutting machine. Laser-guided weapons have high precision, relatively simple structure, and are not susceptible to electromagnetic interference. They occupy an important position in precision-guided weapons. In the early 1970s, the laser-guided aerial bomb developed by the United States was used for the first time on the battlefield in Vietnam. Since the 1980s, the production and equipment of laser-guided missiles and laser-guided shells have also increased day by day.
