DCF-YB-7/128-FA at a glance
Key specifications
-
0.9 ± 0.2
Cladding Absorption @ 915 nm (dB/m)
Wide, flat absorption from 910 nm to 970 nm - reduces pump cooling requirements and allows 940 - 960nm pumping.
-
7 ± 1
Core Diameter (µm)
Diameter of the light-guiding core.
-
0.19 ± 0.02
Numerical Aperture - Core
Easy single-mode operation and low splice loss with passive matching fibers.
-
128 ± 3
Cladding diameter (µm)
Outer diameter of the glass cladding.
-
Min 0.45
Numerical Aperture - Cladding
High-NA cladding that captures and guides the pump light.
-
Typ. 5.4
Cladding Absorption @ 974 nm (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 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 singlemode operation ande 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
- Photodarkening free - ensures stable long-term operation
- Wide, flat absorption from 910 nm to 970 nm - reduces pump cooling requirements and allows 940 - 960nm pumping
Applications
- Pulsed fiber lasers : gain media in preamplifiers or low power amplifiers
- Material processing : laser marking, laser engraving, micromachining and welding
