High-power fiber lasers are being adopted in industry, military and medicine at an unprecedented rate for the past decades over the world. In recent years, there are a lot of reports on ultrafast fiber lasers and their scientific and industrial applications, especially material processing. One part of our current research is on ultrafast high-power Yb doped fiber laser development for scientific, industrial, and medical applications.
We are also interested in ultrafast Tm-doped fiber lasers. Because of high absorption of water at around 2 µm, Tm-doped fiber lasers have earned a lot of applications in hard and soft tissue processing.
Various applications benefit from operation at a central wavelength of 1.5 µm and its second harmonic, including silicon and 3D printing based on two-photon polymerization. Therefore, I put a portion of my current research on this area to develop high power Er-doped fiber laser operating at 1.55 µm.
