What are lasers used for? What is laser used for

Lasers are commonly used in medical cosmetology, freckle rejuvenation, skin rejuvenation, firearms, mechanical fine processing and so on.

There are many uses, beauty, typing, cutting, welding. It's a lot.

Laser applications are very wide, including laser marking, laser welding, laser cutting, optical fiber communication, laser ranging, laser radar, laser**, laser record, laser correction, laser beauty, laser scanning, laser mosquito killer, LIF non-destructive testing technology and so on. Laser systems can be divided into continuous-wave lasers and pulsed lasers.

Laser is another major invention of mankind since the 20th century after nuclear energy, computers and semiconductors, and is known as "the fastest knife", "the most accurate ruler" and "the brightest light". The full English name of the laser has fully expressed the main process of manufacturing the laser. The principle of laser was discovered by the famous American physicist Albert Einstein as early as 1916.

Femtosecond lasers are used in a wide range of applications, such as the ability to penetrate the atmosphere, create discharge channels, and be used for artificial lightning guidance to avoid natural lightning strikes on aircraft, rockets, and power plants. Another example:

The femtosecond laser interaction with matter can produce a sufficient number of neutrons to achieve rapid ignition of laser controlled nuclear fission, opening up a new way for human energy sources.

Due to the ultra-high speed and high resolution characteristics of femtosecond laser, it has an irreplaceable role in physics, biology, chemical control reactions, optical communication and medicine.

The main uses of femtosecond lasers are:

1. Early diagnosis of human lesions;

2. Medical imaging;

3. Surgery;

4. Biological in vivo detection;

5. Ultra-small satellites;

6. Ultra-fine processing;

7. High-density information recording and storage.

Laser demonstration (stage effect), laser ranging (velocimetry), laser scanning (surface 3D rendering, roughness, etc.), laser indication, laser rapid prototyping, laser excitation (nuclear fusion, etc.), laser projection, laser illumination (this seems to be a concept), laser marking, selective material removal, etching, engraving, welding, laser anti-counterfeiting.

We are doing laser precision micromachining, which is more understanding, mainly cutting, drilling, etching, notching, marking and so on. Other homes do car skeleton welding, sheet metal cutting and so on.

Lasers also have laser ranging, laser cutting, laser pointer uses, and so on.

Laser applications are very extensive, and the optical particle network is classified by laser applications, including fiber laser, solid-state laser, laser welding, laser cladding, laser quenching, laser display, laser night vision, laser medical and cosmetology, etc. With the development of science and technology, the application of laser technology can be seen everywhere in life. Hope the light particle network is helpful to you.
