The laser pointer is the atomic stimulated radiation, known as the "fastest knife", "the most accurate ruler", "the brightest light". Laser applications are widely used, mainly laser marking, laser welding, laser cutting, laser radar, laser weapons and so on.
Since the brightness of ordinary light sources is not high, the use of light energy for destruction can only be achieved within a very short distance and the range is small. After the emergence of the laser, the idea of optical weapons was realized.
The laser can be used as a directional weapon, using a powerful directional laser beam to directly damage or invalidate the target. It is a high-tech new concept weapon that uses the enormous energy carried by high-brightness laser beams to destroy or kill targets such as enemy aircraft, missiles, satellites and personnel. The laser pointer can also be used as a short-range tactical weapon. The target includes tanks, aircraft and short-range missiles ranging from a few kilometers to tens of kilometers. The form can be air-to-air, air-to-ground, ground-to-ground, ground-to-air, Ship to air, etc., with high accuracy and destructive power in its effective range.
In addition, there are many applications for lasers. In agriculture, laser breeding can be achieved by irradiating a certain dose and a certain time on a specific part of the crop seed with a laser. Laser breeding is safe and simple. After irradiation, it can accelerate the germination of seeds, increase the germination rate, accelerate the maturity and increase the yield. In biological research, cutting cells with a laser knife has become a reality. In environmental protection, lasers have become an effective tool for monitoring atmospheric pollution.
Laser pointer technology has brought huge benefits to people, and it will be an important area for countries to compete in the new technological revolution.
