Intelligent High-Tech - Laser, How Is It Applied In Life
With the rapid development of science and technology today, the application of laser technology has spread all over our lives and is closely related to us. But when it comes to laser, many people may be unfamiliar, so today, let’s talk about this, a high-tech product that is both familiar and unfamiliar to us—laser.
Laser theory was discovered by the famous physicist Einstein in 1916. It is a kind of light that is strengthened by stimulating radiation. Ratio, total intensity, and intensity spatiotemporal distribution are displayed.
After 42 years, that is, in 1958, it was successfully manufactured for the first time. Today, this great invention has been widely used in military, communication, science and technology, measurement, medical treatment, industry, agriculture and many other fields, and has made these fields happen. Advance by leaps and bounds, even earth-shaking changes.
Application of laser technology in military
Laser technology has covered many fields in the military: such as reconnaissance and positioning, communication, guidance, fire control, laser weapons, etc.
1) Laser guidance: can be used until the target is destroyed. Laser guidance has high precision and strong anti-interference ability.
2) Laser ranging and laser radar: It has the advantages of far, accurate, fast, anti-interference, and no blind spots.
3) Laser reconnaissance and confrontation: use the optical lens to receive reflected echoes, conduct optical scanning reconnaissance on the enemy, and use laser blinding weapons to destroy them, or use jammers to interfere with their normal work.
4) Laser weapons: laser aiming solves the problem of aiming at night;
Application of laser in medical field
With the continuous development of laser technology, laser technology has been perfectly applied in the medical field.
For myopia, surgical treatment generally starts from two aspects, one is to replace the lens with different curvature, and the other is to change the diopter of the cornea. However, replacing the lens is not realistic for young people, but traditional surgical methods cannot achieve the effect of changing the radius of curvature of the cornea. After experiments and research, it is known that the radius of curvature of the cornea should be changed within 3mm of the center of the eyeball. Laser technology can do this because it can be tuned within the molecular size range.
Laser marking technology
Laser marking: It is to use laser to partially irradiate the workpiece to be marked, so as to leave delicate, permanent and clear marks.
The advantages of laser marking machine applications are:
1) Laser marking can make a variety of characters, symbols and patterns, etc., and can be accurate to microns, which makes it difficult for counterfeiters to change, thus playing an anti-counterfeiting role.
2) There is no contact with the workpiece, no cutting force, and little thermal influence, which can ensure the original precision of the workpiece, and can be made on the surface of workpieces of various materials, with fine marking and excellent durability.
3) When laser processing and computer numerical control technology are networked, efficient automatic processing equipment is formed, which can achieve simple operation, easy modification and high efficiency.
4) The laser marking machine also has the advantages of no pollution and low cost, which opens up broad prospects for modern processing and production.
At present, in addition to the above applications, laser technology also involves precision cutting, welding, drilling, engraving, measurement, energy saving and environmental protection, aerospace and other technical fields.
