From the perspective of market size alone, the laser industry seems a bit insignificant; however, the application of laser technology can cover almost all areas of production and life, from automobile manufacturing, power batteries, mobile phone manufacturing, aerospace, medical equipment, and even military and defense. Lasers are active in all areas imaginable; and for many industries, laser technology has become an indispensable supporting technology. As we all know, the core of Made in China 2025 is intelligent manufacturing. One of the cores of intelligent manufacturing is optoelectronic technology, and one of the cores of optoelectronic technology is laser. Therefore, although the market size of the laser industry itself is small, it is a core force driving the development of the manufacturing industry, and its importance is self-evident.

From the perspective of market growth, according to the type of laser, in the next five years, the fastest growing market will be direct semiconductor lasers, mainly high-power semiconductor lasers in the kilowatt class; the second fastest growing will be quantum cascade lasers. This laser advantage Obviously, it has a wide range of uses, especially in counter-terrorism and security applications. It will have a huge demand for quantum cascade lasers in the world in the future. Fiber lasers will always maintain a steady growth rate.

From the perspective of the laser application market, except for the optical communications market, which currently occupies about half of the country, the current macro-material processing is the largest market, followed by micro-processing. In the future, as the manufacturing industry continues to develop to the high end, the micro-processing market will have a large growing space.

The lasers used in laser micromachining applications are mainly excimer lasers, fiber lasers, CO2 lasers, and solid-state lasers, of which fiber lasers and excimer lasers are most commonly used. It is worth mentioning that CO2 lasers have not died out of the market. In fact, many new opportunities have recently been ushered in non-metal processing.

 Laser development trends

As a core driving force in the field of industrial manufacturing, laser technology itself is constantly developing. In summary, lasers are developing in four directions: "faster, higher, better, shorter."

Higher: The laser power is getting higher and higher, and the average power has exceeded 100,000 watts. In 2013, the first commercial 100,000-watt fiber laser was installed at the NADEX Center in Nagoya, Japan, for welding 300mm thick steel plates. Laser cutting applications are also moving towards higher power. The power of laser cutting machines continues to rise, reaching 8 to 12 kW.

Better: The quality of the laser beam output is getting better and better, and the fiber laser's beam quality has reached 100,000-watt single-mode. In the past year, the brightness of fiber lasers, disc lasers, and direct semiconductor lasers have all improved significantly.

Shorter: The output wavelength of the laser covers a shorter wavelength band, and short-wavelength lasers have been widely used. Many advanced manufacturing processes require cold processing. For example, in the manufacture of smart phones, many times need to use short-wavelength, short-pulse UV lasers for processing. The short-wavelength laser has been widely used in the fields of surface marking, semiconductor wafer processing, drilling, and cutting.

Faster: The pulse speed of the laser is getting faster and faster, and the ultra-fast laser has made rapid development. With its simpler structure, more convenient operation, lower cost and more stable performance, it has stepped out of the laboratory into industrial applications.

Future potential markets

Regarding what new application growth points will be in the future market, it has always been a topic of concern to everyone.

Laser cleaning: With the increasing awareness of environmental protection, various environmental cleaning technologies have emerged at the historic moment, and laser cleaning technology is one of them. Laser cleaning uses a high-energy laser beam to interact with the material to be removed on the surface of the workpiece, and instant evaporation or peeling occurs without the need for various chemical cleaning agents, and it is green and pollution-free. Can be used to remove paint, oil stains, oxide layers, cleaning screws, derusting, cleaning welds, etc. Laser cleaning has huge market space in the fields of microelectronics, construction, nuclear power plants, automobile manufacturing, medical treatment, cultural relics protection, steel derusting and mold decontamination, automobile manufacturing, and construction.

Laser radar: The lidar market will grow steadily in the next five years. The main driving force for market growth will come from drones, autonomous vehicles, robotics, military, and security.Laser lighting: Part of the market for laser lighting is automotive laser lighting, mainly automotive headlights. Well-known car manufacturers such as BMW and Audi have adopted laser lighting systems. Another segment of the market is safety laser lighting, such as warning signs for people riding at night.

Laser welding: Laser welding will first be rolled out in the fields of automobile manufacturing, high-speed train and aircraft manufacturing, agricultural machinery and shipbuilding, which will be a future growth point.

Summary of trends

The research and development of lasers are moving towards high intelligence, high power, high beam quality, high reliability, low cost and all solid state.

Laser precision machining and micromachining technology will be the focus of development. Its further promotion and use in electronics, semiconductor, communications, optical storage, micromechanical manufacturing, biology, environment and other industries will create unprecedented possibilities for traditional machining methods. Here, ultrafast lasers will grow rapidly with the expansion of the precision machining and micromachining markets.

The level of automation, integration and intelligence of laser processing has continued to increase. Based on the combination with industrial robots, three-dimensional processing such as welding, marking, and cutting has been realized. The applicability and application of laser technology have continued to expand.

The application of laser technology in industry has become ubiquitous, and new laser technologies are constantly emerging; ultra-fast lasers are becoming industrial lasers, and the market will blow out; direct semiconductor lasers are entering the application market of solid-state lasers; laser 3D printing is developing rapidly, and many key issues Pending breakthrough; laser welding will usher in a period of rapid growth; the combination of photons and semiconductors will produce the next generation of optoelectronic technology; optoelectronic technology has become the support for economic development in the next 30 years; intelligence and manufacturing in China 2025 will bring the laser industry dividend. The next 30 years will be the golden age of laser technology!
