Development prospect of laser industry

Development prospect of laser industry

Laser is another major invention of mankind since the 20th century, after nuclear energy, computer and semiconductor. It is called "the fastest knife", "the most accurate ruler" and "the brightest light". Laser refers to the light emitted by atoms, so it is called "laser". When the electrons in the atom absorb energy and transition from low energy level to high energy level, and then fall back from high energy level to low energy level, the released energy is released in the form of photons. Photon beams (lasers) induced (excited) have highly consistent photonic optical properties. Therefore, compared with ordinary light source, laser has monochromaticity, coherence, high brightness and high directivity. Laser is widely used, including laser marking, laser welding, laser cutting, optical fiber communication, laser ranging, laser radar, laser weapons, laser records, laser orthopedics, laser beauty, laser scanning, laser mosquito killer, LIF non-destructive testing technology, etc. Laser system can be divided into continuous wave laser and pulse laser.

According to the analysis of China's laser industry by the Chinese Academy of Sciences, it is found that China's laser industry is mainly concentrated in South China, of which Guangdong and Fujian are the gathering places of laser industry, representing the highest level of development of China's laser industry. At present, the scale of laser industry in South China has exceeded 20 billion yuan. In central China, a laser industry with Wuhan as the core has been formed. In recent years, the laser industry in this region has developed rapidly, which has strongly driven the economic development of this region. Secondly, the laser industry is developing rapidly in East China, Northeast China, North China and other regions. According to the analysis of the Chinese Academy of Sciences, China's laser industry still has huge development space, which is one of the important driving forces for China's economic development in the future. In recent years, new technologies in China's laser industry are also emerging. As a high-tech industry, the development of the laser industry requires the application of a large number of advanced technologies. Therefore, laser enterprises have also invested a lot of money in technology research and development. In 2019 alone, China's laser industry has nearly 10000 patent technologies. 

According to the data released by the world famous journal LaserFocusWorld, the global semiconductor laser market in 2020 will be 6.724 billion US dollars, an increase of 14.2% over the previous year. With the development of global intelligence, the growing demand for lasers in smart devices, consumer electronics, new energy and other fields, as well as the continuous expansion of emerging applications such as medical and beauty instruments and equipment, semiconductor lasers can be used as the pump source of optical pumped lasers, and their market size will continue to maintain stable growth. In 2021, the global market size of semiconductor lasers is expected to exceed US $8 billion, with a market growth rate of more than 18%. Fiber lasers have made great progress in output power, beam quality and brightness. They have an absolute advantage in the field of material processing and gradually occupy the market of gas and solid lasers, becoming the first choice of industrial lasers, achieving leapfrog growth. In 2020, the scale of China's fiber laser market will be about 9.5 billion yuan, with a year-on-year growth of 15%. It is estimated that the fiber laser market will continue to maintain a growth rate of 15% in 2021, and the market scale is expected to exceed 10 billion yuan.

On the whole, China's laser industry market is developing steadily, and there is still much room for development. According to the research and analysis of China Academy of Commerce and Industry, China's laser industry has a good prospect in the future. The laser processing equipment industry is an industry strongly supported by the Chinese government. In recent years, the Chinese government has strongly supported the development of the manufacturing industry, and encouraged the manufacturing industry to use new technologies to promote intelligent manufacturing. Laser processing can better control processing, and can also be combined with computer numerical control technology, robot systems, etc. to improve product quality, improve production speed, shorten product production cycle, etc, The laser processing and manufacturing industry has a broad future. Under the guidance of government policies, this industry will maintain a trend of rapid growth. The application scope of laser equipment in China is also expanding. With the upgrading of China's industrial structure and the increase of personalized demand, laser equipment has been applied in many fields. In addition, as a new technology, laser processing technology can be integrated with other technologies to produce new technologies, so as to upgrade and transform the traditional manufacturing industry. In addition, China's electronic industry and automobile industry are also developing constantly. The application of laser technology in these industries can improve product accuracy and quality, and achieve the continuous development of the industry.
