Thulium-doped optical fibers and components for fiber lasers in 2 ?m spectral range

Thulium-doped fiber lasers are attractive light sources in the infrared region at around 2 micrometers. Their slope efficiency may reach 70 % and thus they are challenging the well-established ytterbium-doped fiber lasers operating at around...
