High-power fiber lasers have become a critical tool for industrial machining and welding, which has helped to drive market value of industrial fiber lasers to well over ~$2B in 2018. Pulsed lasers have also made significant inroad in semiconductor wafer cutting and trimming. There is currently a significant drive to increase the average power of pulsed lasers for higher throughput, typically in the range few hundreds of watts, an area where fiber lasers excel.

There are also many promising future applications which require pulsed fiber lasers with average powers in the many kWs. One is to generate significant amount of light at extremely high frequency through higher-harmonic generations for applications such as photolithography in advanced semiconductor manufacturing. Another is light-particle accelerator. In this webinar hosted by the OSA Fiber Optics Technology and Applications Technical Group, Liang Dong from Clemson University will briefly cover some historic background, current and emerging applications, recent developments of high-power fiber lasers in both near-IR and mid-IR, as well as key challenges and issues.
