Core Numerical Aperture
Easy single-mode operation and low splice loss with passive matching fibers and HI 1060 standard.
-
128 ± 3
Cladding Diameter (µm)
Outer diameter of the glass cladding.
-
Min 0.45
Cladding Numerical Aperture
High-NA cladding that captures and guides the pump light.
-
(7.8)
Cladding Absorption @ 975 nm (nominal) (dB/m)
Pump light absorbed per metre by the doped core, measured through the cladding.
Description
This phosphosilicate fiber is ideal as a gain medium for lower power amplifiers or the pre-amplifier stage and is mainly used in a MOPA configuration of a pulsed fiber laser. On top of all the benefits found in a phosphosilicate fiber (high saturation energy, photodarkening-free performance and high absorption), this fiber shows easy single-mode operation and very low splice loss when matching with standard fibers such as HI 1060.
Features & Benefits
- Easy single-mode operation and low splice loss with passive matching fibers and HI 1060 standard.
- Photodarkening-free – ensures stable long-term operation
- Wide, flat absorption from 910 nm to 970 nm – reduces pump cooling and allows 940-960 nm pumping
Applications
- Pulsed fiber lasers: gain media in pre-amplifiers or low power amplifiers
- Material processing: laser marking, laser engraving, micromachining and welding
