SM-TDF-10P/130-M, Matched Tm-Doped Double Clad Optical Fiber
Coherent thulium-doped double clad fibers utilize glass compositions specifically optimized for high cross-relaxation rates between Tm ions, enabling efficient conversion of 793 nm pump photons into signal photons at 2 µm. The precision matched -M fiber version offers higher absorption and efficiency than the -HE version. The waveguide design in the -M version is tailored for single-mode operation in monolithic fiber laser/amplifier systems when spliced to precision-matched passive fibers. These fibers, along with matching passive fibers, are available in a 130 µm cladding diameter for ease of handling, cleaving, and splicing, enabling reliable manufacturing of low-power, eye-safe fiber lasers and amplifiers.
