Status of laser industry: market growth slows, stronger competition
In recent years, China's laser industry has flourished, especially the laser is the most. As one of the indispensable core components in the laser processing system, lasers are widely used in material processing, communication, information processing, medical beauty, research military, and other industrial manufacturing areas.
According to data, the global laser market has continued to grow in 2013-2019, and the 2019 global laser market is 15.13 billion US dollars, an increase of 1.3% year-on-year. As the market growth slows slowly, the industrial development has gradually revealed: the product is more serious, the market price is unordered, the product gross profit margin has fallen sharply, and the survival environment of SMEs is more difficult .
With the demand for high-end industrial manufacturing, domestic enterprises have also continuously increased research and development investment to explore new technical routes, seeking breakthroughs through differentiation layouts to construct new advantages, in order to be in the laser industry in Fengyun Prior to the machine.
At present, there are two mainstream routes of laser technology research and development: First, the vertical expansion of laser power performance, that is, through breakthrough technology bottlenecks, it is constantly increasing the output power, reducing prices, and promoting efficiency, to increase product market competitiveness; second, new lasers Transverse expansion, that is, develop new laser types through new light sources, media, structures, etc. to develop new application scenarios to open new markets.
Along with the watt-level fiber laser in the market such as the rain, the homogeneous competition allows the improvement of the product to gradually touch the ceiling, and the vertical high-power superposition route is more difficult. Therefore, more manufacturers have turned to seek the horizontal breakthrough of new lasers, and in many broken directions, "Blu-ray lasers" in recent years have generally believed that a new laser is worthy of attention.
Differentiation breaks: Blu-ray lasers become focus at home and abroad
The blue-ray laser is a laser located in a blue band source, and its wavelength is about 400 nm-500 nm, and the industrial grade blue laser is generally a semiconductor laser. Blue light lasers have short wavelengths, small diffraction effects, energy and high characteristics, in material processing, optical information storage, display technology, communication technology, laser medical, etc. have broad application prospects.
It is well known that there is three primary color-red-green blue (RGB), and the most used in the domestic market is the fiber laser in which the wavelength is infrared. Compared with the red green laser technology, it has long matured and realizes industrial application. The blue laser is due to materials, costs, technology, etc., the power has been relatively lagging after several tiles, and the fiber-optic laser that is 10,000. Become the bottleneck of laser technology development.
The blue laser starts late. In 2015, the German semiconductor laser manufacturer Dilas first launched a blue-ray visual optical semiconductor laser system having a wavelength of 450 nm, with a maximum output power of 25 watts, and the fiber core diameter is 200 μm or 400 μm, which can be extended to 100. Watts, can be used for material processing; in the same year, Japan Shimadz Company announced successfully developed fiberly coupled high-brightness Blu-ray direct diode lasers "Blue Impact", using blue-ray gallium nitride semiconductor lasers, is the world's first product chemicalized laser processing light source.
New technology route realizes "no splash welding", more infrared light efficiency is at least 8 times
It is understood that the Guangdong Hard Academy is approved by the Guangdong Science and Technology Department, organized by the Guangzhou High-tech Industrial Development Zone Management Committee, relying on the Chinese Academy of Sciences, Xi'an Optics Precision Machinery Institute, the provincial new research and development institutions jointly co-constructed . Its Blu-ray laser research and development team is affiliated with the Optoelectronic Technology Innovation Center of the Hard Academy. It is a senior sea from the deep-cultural industry, and has experienced experience in optical, structural, electrical, and crafts. Through the contrast of the research and technology route in the laser processing market, the team discovered: compared to infrared light, Blu-ray more innate advantages in the field of material processing.
According to the Chief Scientist of the Hard Academy: "The infrared laser exhibits excellent in many industrial use fields, but is not ideal in high-counter metal processing in the corresponding band, and blue light is 10-20 times the absorption of the same material. At the same time, it can improve the splash problem caused by infrared laser processing by blue laser processing. "
The Blu-ray laser independently developed by the Hard Department is an example. When the most common "copper" in the processing industry is "copper", if the power required to use conventional infrared lasers is about 4000 watts, the blue laser is only 400-800 watts. At the same time, the high absorption rate of copper metal is greatly increased by the high absorption rate of blue light, and the welding effect can be subjected to the welding effect by parameter control, and the "no splash welding"; in addition to quality, Blu-ray welding copper metal It also has a significant speed advantage, at least 8 times faster than infrared laser welding.
Industrialization application: innovative high anti-material processing field, new energy battery, 3C advantage
Although the Blu-ray laser is a rookie in the field of laser, there is a significant advantage in the field of high and anti-material processing. At present, there is a gradual temporary angle in the field of new energy battery welding, 3C and alloys.
For example, in the welding of lithium electronic batteries, the Blu-ray laser is perfectly adapted to apply the scenario. The lithium ion battery achieves a high energy density by hierarchically layered a plurality of thin copper sheets and aluminum sheets, wherein the connection of the multilayer electrode sheet and the welding of the battery extract can be welded using a blue laser. Ultrasonic welding and infrared laser welding speed are faster, and the consistency is also better; there is no splash of pollutants during the welding process, and it is also effective to avoid problems such as battery short circuits, affect performance safety.
Blue lasers are also suitable for large quantities of electronic products, such as mobile phones, tablets, and computers - any application with copper as main components. Blue lasers have proven their advantages in welding copper, stainless steel and aluminum. In fact, the blue laser also applies to low / no defects between thin metals.
In addition, the Blu-ray laser is gradually attracted by the market in the fields of display, storage, detection, and medical care.
Of course, there is still a shortcoming of blue lasers, which is the current power density, which is also the actual situation of international and domestic blue lasers. I believe that as research is in-depth, this issue will gradually improve.
With the "14th Five-Year Plan", the domestic laser industry will get a greater development space, and it is imperative to get rid of homogenization competition. The Blu-ray laser is an emerging technology route, although it is still in the early stages of development, but it has been in the field of high reaction processing. As the laser industry is converted from the high-speed development stage to high quality development stage, the differentiated barriers have gradually appeared, and the Blu-ray laser will also show more possible in the high-precision industry.
