Coherent Thulium-doped double clad fiber utilizes a glass composition specifically optimized for highly efficient operation around the important 2 µm wavelength when pumped at ~793 nm. These small core fibers facilitate highly efficient single-mode operation while the telcom-like 130 µm cladding diameter makes handling, including cleaving and splicing, as simple as possible.
