Thulium high-power Q-switch & QCW (2μm)
A central emission wavelength of 2 µm generated by Thulium-doped amplifiers has enabled a multitude of new applications. AFS offers the highest performance among commercially available 2-µm fiber-based ultrafast laser systems.
AFS ultrafast fiber lasers are characterized by an outstanding performance combined with flexibility and maximum stability. All essential parameters are software controlled and can be tuned over a wide range, making them an extremely valuable tool in many applications.
