FDA-regulated laser pointer
Lasers do not necessarily work in the visible spectrum. Laser pointers provide targets for laser-guided missiles or bombs, such as the Paveway manufactured by Raytheon and the AGM-114 Hellfire missile by Lockheed Martin. These aerial munitions detect laser spots, whose frequency is very specific, and have a fixed trajectory on them. The beam seen is small enough to be carried in a pocket or key chain. The design is usable when the laser pointer and the functional writing pen are installed together. The pointer being manufactured can project patterns of stars, circles, squares and traditional circular patterns. Although most of these devices contain warning labels, many devices are incorrectly labeled as "safe" as required by FDA regulations. Currently, there are no purchase restrictions, nor is there any now anyone can buy a green laser pointer. If it is handled carelessly, it may be potentially dangerous.

The problem of laser attacks on aircraft was born in the United States in the late 1990s, and then assumed to be a true epidemic proportion in recent years. According to Valeri Chelkovnikov, Chairman of Flight Safety Analysis and Consulting Agency, the Federal Aviation Administration recorded more than 2,800 laser attacks in the first half of 2011. As for the astronomical high power laser pointer, it is a light laser whose beam can be focused and burned. In addition, because the light is bright and very clear, astronomers like to point at the stars and constellations with a green laser pointer. Russian experts will be able to familiarize themselves with the experience of American special services at a seminar on the purchase of high-quality lasers for civil aviation held at Eurocontrol headquarters in Brussels in October. During the meeting, representatives of various countries will also discuss the possibility of adopting joint measures to reduce the use of laser equipment that causes nuisance to aviation. Boeing YAL-1 airborne laser: The system consists of a chemical iodine oxygen laser (Chemical Oxygen Iodine Laser: COIL) with a power of 1 MW, a telescope diameter of 1.5 meters, and a weight of 5443 kg. It is installed on the turret on the nose of the aircraft. . ABL uses infrared sensors to detect missiles. Then, three low-power lasers track the missile and atmospheric disturbances to determine its position and velocity.
