LMA-TDF-25P/250-LC, Tm-Doped Double Clad, Optical Fiber

SKU LMA-TDF-25P/250-LC
UOM Meter(s)

The first true LMA fibers featuring a unique low NA (0.1) Tm-doped core design and fully optimized for high slope efficiency when pumped at 793 nm. This extraordinary efficiency is due to composition enabled cross relaxation of Thulium ions in the core. Both fibers fearure a 25 µm core and a 250 µm clad daimeter design allowing for a large mode field diameter and short device lengths thereby minimizing non-linear effects such as SBS and SRS. The - HE fiber features a high Tm-concentration with high pump conversion efficiency optimized for operation in the higher 2 µm wavelength gain spectrum. The -LC fiber features a lower concentration Tm-concentration that operates in the shorter wavelength region of the gain spectrum with improved performance.
