According to the “Hubei Daily” headline news, the laser energy released through a fiber of the same thickness as an embroidery needle is powerful enough to weld the aircraft and the ship. It was reported yesterday that China’s first ten-thousand-watt CW fiber laser was presented to the public in the Optics Valley of China, making China the second country in the world to have mastered this technology following the United States.

Yesterday, the reporter saw the laser in the Research and Development Center of Wuhan Raycus Fiber Laser Technologies Co., Ltd. The laser device, although only about the size of two overlaying freezers, has hidden in its stomach 10 “energy cubes,” each able to generate a laser beam of 1,100 watts. The 10 laser beams then converge into an optical fiber to form composite force, ultimately generating ten thousand watts of powerful energy – this laser beam convergence technology is considered by the United States as the core secret of the ten-thousand-watt laser.

It is reported that, in order to break the monopoly, Yan Dapeng and Li Cheng, two experts from the national “Recruitment Program of Global Experts” (1,000 Talent Plan) led a team and spent one year to tackle key problems and finally obtained the independent intellectual property rights of the technology.

It is understood that in the international arena, fiber lasers are more and more widely used in industrial shipbuilding, automobile manufacturing, aerospace, military equipment and other fields. Compared with the traditional carbon dioxide laser, the fiber laser is only 1/5 in terms of power consumption and only 1/10 in terms of size, but is four times faster and with 20% higher conversion efficiency, and in addition, free of pollution.

Yan Dapeng, the chief engineer of Raycus, said China has long been relying on importation from the United States for the need of several thousand units of high-power fiber lasers each year, at the price of RMB 5 million yuan per unit. “Beijing University of Aeronautics and Astronautics has begun to contact us, and we have at hand four other purchase orders scheduled for production,” said Yan.

Zhou Bingkun, the chairman of Chinese Optical Society and academician from Chinese Academy of Science said that the Optics Valley takes the lead in this technology in the world, second only to the United States, and will greatly boost China’s industrial development. In the past, China mainly relied on importation for core laser devices. With the ten-thousand-watt fiber laser, many technical difficulties can now be overcome. The enterprise’s independent innovation spirit is commendable.

According to reports, the technology has been incorporated into the next year’s National High-tech R&D Program, or known as the “863 Program”. Yan Dapeng said, “We have confidence to make breakthroughs in the twenty-thousand-watt technology and realize output value of RMB 160 million yuan within this year.”
