Phosphosilicate Fibers

Ytterbium fibers are subjected to transmission losses known as photodarkening, which translates in the degradation of power over time.


Coractive has developped and manufactured phosphosilicate optical fibers which nullify this photodarkening phenomenon providing long-term stability of the output power.


Moreover, these fibers offer high saturation energy (twice as much as standard aluminosilicate glass fibers) and high absorption that allows shorter fiber length to be used thereby reducing nonlinear effect threshold.
