Ultrastable and ultrafast mid-IR laser sources
u.MIR Research Group @ Wroclaw Tech
Welcome to the webpage of ultrastable and ultrafast mid-infrared laser sources (u.MIR) research group!
We are u.MIR:
We build ultrafast Cr:ZnS/Se lasers, we stabilize them to ultrastable frequency combs, and we use nonlinear optics to convert their radiation to mid-infrared range. Read more about our research »
The Group is led by Maciej Kowalczyk at Wroclaw Tech. We are a part of the Laser & Fiber Electronics Group at Faculty of Electronics, Photonics and Microsystems.
Our research is co-funded by the European Funds for Smart Economy 2021-2027 (Priority 2) within the FIRST TEAM FENG programme.
