Optical cable LMA-HDF-40/400

True LMA fiber featuring a unique low NA (< 0.1) high concentration Ho-doped core design. The Ho-doped fiber can be pumped by a Tm-doped fiber laser at ~1950-nm and can achieve 60% efficiency. The high NA (0.46) large pump cladding waveguide allows for efficient coupling of high pump powers. The large core diameter (40 μm) maintains a large mode field diameter and short device length, thereby minimizing non-linear effects such as SBS and SRS.
