DCF-YB-12/128P-FA at a glance
Key specifications
-
3.0 ± 0.5
Cladding Absorption @ 915 nm (dB/m)
Large core diameter with high pump absorption – allows a shorter fiber length for a more compact and less expensive design while reducing non-linear effects.
-
12 ± 1
Core Diameter (µm)
Diameter of the light-guiding core.
-
0.08 ± 0.01
Core Numerical Aperture
Light-acceptance angle of the core; with the core size, it sets how many modes are guided.
-
128 ± 3
Cladding Diameter (µm)
Low splice loss with standard fiber such as HI1060.
-
> 0.45
Cladding Numerical Aperture
Wide, flat absorption from 910 nm to 970 nm – reduces pump cooling and allows 940-960 nm pumping.
-
(18)
Cladding Absorption @ 975 nm (nominal) (dB/m)
Pump light absorbed per metre by the doped core, measured through the cladding.
Description
This phosphosilicate Yb-doped double-clad fiber offers high doping concentrations and high QCE values that ensure minimum fiber length, minimum pump power and reduced non-linearities. With all the benefits that phosphosilicate fibers have to offer, such as high energy saturation and no photodarkening, it is the perfect solution for a wide range of demanding pulsed laser and amplifier applications in the industrial and medical markets.
