Laser is another great invention after nuclear energy, computer and semiconductor since the 20th century. It is called "the fastest knife", "the most accurate ruler" and "the brightest light". The light excited by atoms is named "laser";

When electrons in atoms absorb energy, they jump from low energy level to high energy level, and then fall back from high energy level to low energy level, and the released energy is released in the form of photons.

The induced (excited) photon beam (laser) has highly consistent photon optical characteristics. This makes the laser have better monochromaticity, higher brightness and better directivity than ordinary light sources.

Laser is widely used, including laser marking, laser welding, laser cutting, optical fiber communication, laser ranging, laser radar, laser weapon, laser recording, laser correction, laser beauty, laser scanning, laser mosquito killer, LIF nondestructive testing technology and so on.

Basic requirements of laser processing

In order to adopt laser processing technology, the manufacturing industry requires laser processing equipment to meet the following requirements:

(1) can meet the use requirements: it can improve product quality or manufacture new products, and enhance the competitiveness of enterprises;

(2) Reliability: it can run in industrial environment, work continuously for 24 hours, and can be operated by ordinary skilled workers;

(3) Safety: the equipment has good safety, and no personal injury or other accidents that cause losses to the enterprise will occur during use;

(4) Short payback period: It requires good equipment performance, reasonable price, less energy consumption and small floor space, so that enterprises can achieve higher economic benefits with less investment and lower operating costs.
