With the development of technology, my country has introduced advanced equipment such as laser processing from abroad in recent years. The laser processing industry is developing rapidly in China. The high-tech term of laser is no longer unfamiliar and invisible. Now most of the traditional The processing industry is reforming and renewing, joining the queue of the laser processing industry.
The laser industry has formed a complete and mature industrial chain distribution. The upstream mainly includes laser materials and supporting components, the midstream mainly includes various lasers and their supporting equipment, and the downstream mainly includes laser application products, consumer products, and equipment. The domestic laser market mainly includes laser processing equipment, optical communication devices and equipment, laser measurement equipment, lasers, laser medical equipment, and laser components. .
As a new type of light source, laser has the characteristics of good directionality, high brightness, good monochromaticity and high energy density. The laser industry based on lasers is developing rapidly around the world, and now it has been widely used in industrial production, communication, information processing, medical and health, military, cultural education and scientific research. According to statistics, from high-end optical fibers to common barcode scanners, the market value of laser-related products and services is as high as trillions of dollars each year.
At present, my country’s laser cutting machine industry is mainly used in laser processing, medical and other industries, of which 12% is in the field of scientific research and development, 32% in the field of material processing, 12% in the field of communication, 14% in the field of information, 20% in the field of medicine, and 20% in the field of measurement. And other fields accounted for 9% and 1% respectively.
Up to now, there are 5 national laser technology research centers and more than 10 research institutions in the country; 21 provinces and cities produce and sell laser products, and there are more than 200 units that produce and sell stereotyped products all year round and form a certain scale. . The domestic laser industry has formed a relatively complete industrial chain consisting of laser crystals, key components, accessories, lasers, laser systems, application development, and public service platforms.
my country’s laser processing industry can be divided into four industrial belts, the Pearl River Delta, the Yangtze River Delta, Central China and the Bohai Rim. The focus of these four industrial belts is different. The Pearl River Delta is dominated by small and medium-power laser processing machines, the Yangtze River Delta is dominated by high-power laser cutting and welding equipment, the Bohai Rim is dominated by high-power laser cladding and all-solid-state lasers, and Wuhan is the leader. The central China area covers large, medium and small laser processing equipment.
With the transformation and upgrading of China’s manufacturing industry, some old industrial bases and small business bases have begun to transform into high-end manufacturing fields. For example, Wenzhou laser industry cluster and Anshan vigorously develop laser industry.
Innovation
The construction of innovation bases is the guarantee for the sustainable development of laser technology industrialization. From the “Sixth Five-Year Plan” to the “Ninth Five-Year Plan”, the state has listed laser technology as a special project and paid special attention, which is why China’s laser industry is booming today. Now, the development speed of laser technology and industrialization in the world is extremely fast. There are more and more mature technologies in gas lasers and application systems. In the field of solid-state lasers, new crystal materials are constantly emerging, and new laser technologies are constantly developing. In order to keep up with the pace of world development and provide continuous technical support and talent support for China’s laser industrialization, it is necessary to strengthen the construction of laser technology innovation bases, especially the construction of engineering innovation bases.
Maintain the technological development trend that is synchronized with the international advanced level, focus on breaking through several key technologies, and solve the bottleneck restricting the development of my country’s laser technology industry. Closely integrated with the main battlefield of national economic construction, with the transformation and commercialization of scientific and technological achievements as the core, it focuses on solving the core key technologies of laser unit devices, system integration and processing technology. Increase the research and development of new products to provide technical reserves for industrial development.
For laser cutting and welding lasers, optical devices, light guide systems and supporting components of laser processing equipment, we continue to provide new technologies, new designs and new prototypes, focusing on the development and production of high-power axial fast-flow CO2 lasers, all-curing YAG lasers, new Movable laser processing machine and composite laser welding technology. The specific measures are as follows:
(1) Establish a common technology research platform for the industry for cutting and welding of automobile sheets; wide-band heat treatment and surface cladding of metallurgical steel rolls, complete sets of laser welding equipment and laser texturing equipment for steel strips in the metallurgical industry; laser processing of underground tubing in the petroleum industry. Solve the localization, serialization, generalization and standardization of key common technologies and supporting equipment.
(2) Establish a new laser research and development platform ① By introducing foreign axial fast-flow CO2 laser technology, the production capacity and product quality of domestic high-power CO2 lasers will be improved, and on the basis of digestion and absorption, high-quality, high-stable, high-power lasers will be launched continuously. CO2 laser. Focus on the development of RF excitation, axial fast flow, and CO2 lasers of more than 10,000 watts. ②Develop high-power, multi-wavelength solid-state lasers (>1kW), 100-1000W diode-pumped solid-state lasers and ultraviolet-band solid-state lasers. Focus on the development of pump modules, and strive to establish a more comprehensive DPSSL production base in China.

system integration
On the basis of the “Ninth Five-Year Plan” and the “Tenth Five-Year Plan” 863 achievements, the “Eleventh Five-Year Plan” focuses on three levels of research and development, including system integration and application, high-stability lasers and new lasers, and partially realize industrialization. .
(1) The integration of system integration is the core of developing Wuhan laser processing industry. A system integrator is a leader in the development of a region and an industry. Only when the strength of the system integrator grows can the entire industry be driven. The purpose of system integrator integration is that each enterprise has its own characteristics and advantages, and there is a certain competitive relationship with each other.
According to the characteristics of the current system integrators, it is advisable to set up various forms of system integrators such as solid-state laser equipment, laser cutting equipment, laser medical equipment, large-scale laser processing equipment and laser processing stations, and the existing business owners become these companies. In the process of integrating existing system integrators, the government should play the role of intermediary and service, create opportunities for companies with mature conditions to go public and raise funds, further optimize the structure of property rights, and lay a solid foundation for further development .
(2) Improve the supply chain to create and grow a group of parts suppliers with core technologies. The foundation of an industry is supported by many component suppliers. For the Wuhan area, such a group of component suppliers should include optical devices (such as optical lenses, focusing mirrors, mirrors and transmission fibers, etc.), precision machining, laser power supplies, and precision electronics. At the same time, these parts supplier groups should have core technologies in this field, which is of great significance to promote the entire laser processing industry. Supporting enterprises are the foundation of an industry, especially those that master core technologies and possess independent intellectual property rights, which are of great significance to the development of the industry.
(3) Introducing and digesting from a high starting point, and encouraging the development of a group of supporting enterprises. First of all, it is necessary to encourage the cooperation between supporting enterprises and scientific research institutions. This is a relatively fast method; secondly, enterprises should keep an eye on the trend of technological development and constantly introduce new ones; , the government can encourage the development of supporting enterprises through the arrangement of scientific and technological project plans, tax policies and other means.
(4) Increase market efforts This requires system integrators to invest more in the promotion of laser processing technology and the establishment of market networks, including developing overseas markets at certain times. Through the promotion and application, technical radiation and personnel training, the establishment of sub-centers, processing stations and joint ventures for laser processing demonstration applications in China will promote the development of my country’s laser processing industry.
(5) Domestic capital of the capital platform: Realize the diversification of equity investment, and introduce listed companies, state-owned investment companies, and private capital; The introduction of foreign capital can start from the supporting industries. After all, foreign capital has technical advantages in most supporting fields related to energy optoelectronics, and the supporting fields of investment are not as large as the investment system integration; Specialized laser processing increases the intensity of financial support, makes full use of the characteristics of domestic economic and social structure, and aims at high efficiency, applies advanced laser manufacturing technology, and develops, designs and manufactures high-efficiency laser processing production lines with international leading levels. Introduce foreign advanced technology and funds, and establish several joint ventures for the production of lasers and complete sets of equipment to improve the level of my country’s laser products.
