News.hust.edu.cn On October 16, the industrial fiber laser sample developed by Professor Ma Xiuquan from the School of Mechanical Science & Engineering and his team broke through the laser power of 30,000 watts for the first time. The sample consists of 6 single-fiber laser oscillators that generates a beam and outputs it through an all-fiber beam combiner from a fiber which is 200 microns in diameter. The BPP of the beam is less than 8 mm-milliradian.

The team has been researching how to combine laser sources with laser manufacturing equipment since 2016. After 2 years of high-intensive technical work, the team released the commercial single-fiber 5000-watt industrial laser module in 2018 and made a series of breakthroughs in the development of key technologies, such as special beam combiner traction, high-power fiber grating engraving and ultra-high-power QBH/QD technology. And the laser power broke through 30,000 watts for the first time this month and the subsequent output power is still rising.

With their exceptional strength in laser technology and manufacturing equipment, the team is also planning to make the best of to apply their 30,000-watt industrial laser soon in the equipment development of marine engineering, aerospace, civil construction, oil exploration and other fields, continuing to strive to meet the country’s major needs.

This progress in the R&D of the laser source is attributed to our School of Mechanical Science & Engineering, which has been devoted to the exploration of laser technology and the development of manufacturing equipment for a long time. This is also the result of our school’s long-term emphasis on talent introduction and interdisciplinary development. Professor Ma Xiuquan is a young scholar introduced into our School of Mechanical Science & Engineering in 2015. Currently, he is undertaking research into high-power fiber lasers and laser manufacturing in the laser processing team of the school.
