Nu2µ - Thulium Fiber Laser

Working at the Optimal Wavelength

Powered by Nufern’s proprietary thulium-doped LMA optical fibers, the Nu2μ laser sources are a valuable choice for OEM medical laser manufacturing. Operation in the eye-safe 1940 nm wavelength range corresponds to a strong molecular water absorption peak, which enables flexible control of the energy absorption in tissue. Near diffraction limited beam quality allows for precisely focused output, and the inherent fiber-optic delivery is ideally suited to minimally invasive procedures. Nufern fiber lasers are compact, highly efficient, air cooled, and maintenance free, and are backed by our years of experience and unique IP.
