Buying Thulium-doped Laser Gain Media
Thulium-doped laser gain media include crystalline materials like Tm3+:YAG and thulium-doped fibers, such as double-clad fibers for high-power operation and fibers for upconversion lasing. These media typically emit in the 2-μm region, with some capable of blue emission via upconversion processes.

![]() Leader in fluoride glass and optical fiber technology Le Verre FluoréRue Gabriel Voisin Campus de Ker Lann 35170 Bruz, Brittany France | ![]() Thanks to their high rare-earth solubility (up to 100,000 ppm) and low phonon energy, LVF fluoride fibers offer dozens of active transitions, enabling a broad range of applications from visible to the mid-infrared. LVF thulium doped fibers are available as single.mode fibers or double cladding fibers. LVF thulium doped fibers can be used for laser emission at visible wavelengths (455 nm, 785 nm), at infrared wavelengths (810 nm, 1.47 µm, 1.88 µm) and mid-infrared wavelengths (2.3 µm). |
