Eye Safe 5/125 Thulium-Doped Single-Mode Single Clad Fiber
This single clad, small core diameter fiber features a very highly Tm-doped core region (~7% Tm) and is ideally suited for core pumping, enabling very short laser cavities required in producing ultra-fast fiber lasers with high slope efficiency under resonant pumping. The 5 µm core diameter with its 0.24 NA, together, offer superior single-mode operation and excellent bending performance.
340.00 ± 50.00 dB/m at 1560 nm
Geometrical & Mechanical Specifications
Coating Requirements: UV Cured, dual acrylate coating.
