In recent years, with the continuous development of laser intelligent manufacturing industry, the demand for upstream laser chips is increasing, among which the representative high-power fiber lasers, ultrafast lasers and solid state/semiconductor lasers are at a high speed in industrial applications. Wuhan Ruijing Laser Chip Technology Co., Ltd. (hereinafter referred to as "Ruijing Laser") has always been following the market application trend, taking the application demand scenario as the traction, relying on years of continuous technical innovation in the market, continuously optimizing and upgrading 915/976nm industrial application products, and can provide customers with a full range of chip application solutions.
After continuous iteration and optimization, the 915/976nm 30W series single tube core products of the sharp crystal laser have been widely used in the domestic mainstream fiber laser market. In order to further meet the demand for high power, the newly developed 300 μ M strip width 9XXnm series products, maximum output power ≥ 50W, conversion efficiency ≥ 54% @ 50W, degree of polarization above 95%.
In addition, the 878nm and 888nm series of single tube core products of the sharp crystal laser, as the pump source of ultrafast fiber and solid state laser and the application of direct semiconductor laser, have attracted extensive attention in the market since their debut. Under the condition of 12A current VBG wave locking application, 878nm and 888nm series products have no failure in the aging test for tens of thousands of hours. The newly developed products can meet the requirements of 16A current VBG wave locking application, greatly improving the beam output quality and stability. This technology is at the leading level in the industry. At present, the market share of this series of products ranks first in China. Under normal temperature, the working power of 940nm series single tube core products can reach 22W. The output power of this product can reach ≥ 6W under high temperature 105 ℃ and 11A current injection. At present, it has been successfully introduced into the client, won widespread trust and recognition from customers, and has made a figure in the vehicle laser Lada market, and has been verified at the vehicle specification level. The market prospect is broad.
At present, the sharp laser bar products have also achieved major technological breakthroughs. The 880nm/940nm single bar can achieve continuous laser output of more than 200W, and can also meet the 700W quasi continuous laser output at low temperatures. The electro-optical conversion efficiency at room temperature can exceed 63% at most, and at low temperatures can exceed 70% at most. The high unity of power and efficiency can be achieved, greatly improving the service life of products, and can meet various requirements of industrial laser systems, The operation cost of customers is significantly reduced. At present, the technical indicators of this product are at the leading level in the industry.
Acrystal Laser has always been aiming at the technological highland of high power semiconductor laser chips. After years of research, development and industrialization accumulation, it has established a full process independent and controllable IDM mode R&D and production platform covering chip design, MOCVD epitaxial growth, wafer processing, cavity surface coating process, automatic chip packaging test, reliability test and verification, led by technological innovation, It has become one of the few large-scale industrialized companies integrating the R&D and production of high-power semiconductor laser chips in the world.
Based on the endorsement of its own key core technology, supplemented by the collaborative design of chip structure and process, the sharp laser has greatly shortened the product development cycle and batch supply cycle, and significantly improved the efficiency of customer demand feedback. Its products have achieved a comprehensive layout of high power, high efficiency, high reliability, high polarization, wide wavelength range single tube chips and Bar products from a single breakthrough to a full bloom. At present, nearly 30 products have been industrialized, and the wavelength covers the full range of 650-1064nm series of high-power laser applications. The performance level of the products is comparable to the world-class.
In addition to standardized products, based on the self controllable ability of the whole industrial chain of R&D, production and manufacturing, the sharp laser can quickly respond to customers' personalized and customized needs, and provide customers with chips and bar products of different wavelengths and performances, as well as COS, TO, and various types of Mount packaging devices. At the same time, it can also provide customers with epitaxial growth and wafer processing OEM services to further enhance the technical added value.
As a large-scale industrialized company, product quality is the foundation of the enterprise. By deepening the integration of information technology and quality management, Ruijing Laser has realized the whole process digital quality control, comprehensively improved the quality management efficiency, greatly improved the product yield and production capacity, and the monthly production capacity has reached millions.
In the future, Ruijing Laser will give full play to the advantages of IDM's integrated R&D and production platform, accelerate the construction of core technology and industrialization capacity, further expand the range and types of chip wavelengths, complete the construction of product matrix, expand emerging application fields, and gradually build itself into an international first-class semiconductor laser chip R&D platform and industrialization company, fully meeting the diversified needs of different application fields and application scenarios.
