Smart Product Number: SM-HDF-10/130
EyeSafe 10 Micron Core Holmium-Doped SM Double Clad Fiber
SM fiber featuring a 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, but with its small core size this fiber can easily be core-pumped as well. This fiber features a single mode large core/cladding ratio with a low NA and is ideally suited for both CW and pulsed laser applications.
