The basis of this technology is a beam of light. When it passes through a special medium (crystal, gas or liquid), it reflects and amplifies between two mirrors until all the beams are running in the same direction. Produces a strong beam of light, called a laser beam. Today, laser technology is used in most technologies. Its application areas range from everyday products such as printers and drives, to industrial applications such as cutting, welding and sintering, to measurement technology, data transmission and medical technology. The price war in the past two years has accelerated the clearance of low-end production capacity in the high power laser pointer processing equipment industry. In the next few years, the vicious competition of price competition will gradually evolve into a competition for talents and application solutions. The construction of a high-level engineer team and service network will bring a huge competitive advantage to the enterprise, and continuous improvement of product quality and technology, and shaping the multi-dimensional competitiveness of the enterprise are the key to the vitality of laser processing equipment enterprises.

In the ruby ​​laser, a high-pressure xenon lamp is used as a "pump", and the strong light emitted by the xenon lamp is used to excite chromium ions to the excited state E3, and the electrons pumped to E3 quickly (~ 10 -8s) transition to E2 through a non-radiative transition . E2 is a metastable energy level. The probability of spontaneous emission from E2 to E1 is very small, and the lifetime is as long as 10-3s, which allows particles to stay for a long time. As a result, the particles accumulate on E2, realizing the population inversion on the two energy levels of E2 and E1. The stimulated emission from E2 to E1 is a red laser with a wavelength of 694.3nm. Regarding the future prospects of the laser processing industry, it mainly includes: conquering the key technologies of green laser pointer manufacturing core components, basically realizing the independent supply of the whole domestic laser manufacturing industry chain; researching and developing intelligent, extreme, high-performance advanced laser manufacturing technology and series of equipment, basically realizing aviation Autonomous supply of the entire industry chain of laser manufacturing technology for high-end equipment such as engines; realization of large-scale industrial applications, with a view to achieving the overall strength of the laser manufacturing and remanufacturing industry to reach the world's advanced level.
