According to Xinhua News Agency reporters Liao Jun and Chen Jun, the laser energy released by an optical fiber with the thickness of an embroidery needle can be used to weld aircraft and ships. The reporter recently learned from Wuhan that China's first 10000 watt CW fiber laser was introduced in Wuhan, and China has become the second country to master this technology after the United States.

　　Although this laser is only about the size of the superposition of two freezers, it has 10 "energy squares" hidden in its stomach. Each 1100 watts produces a laser beam, and then 10 laser beams converge on an optical fiber to form a joint force, and finally produce 11000 watts of powerful energy. This laser power combining technology is regarded by the United States as the core secret of 10000 watt lasers.

　In order to break the monopoly, Yan Dapeng and Li Cheng, two experts of the national "thousand talents plan", led a team to research and develop key problems for one year, and finally mastered the technology. Internationally, 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, its power consumption is only 1 / 5 and its volume is only 1 / 10, but its speed is 4 times faster, the conversion efficiency is 20% higher, and there is no pollution.

　　This technology has been incorporated into the National 863 program next year. During the year, the technical team will also develop 20000 watt technology to achieve the output value of 160million yuan.
