LIEKKI™ Erbium Fibres
nLIGHT offers a broad selection of erbium doped LIEKKI™ fibers for applications ranging from standard telecom & cable TV C- and L- band amplifiers and amplify spontaneous emission (ASE) sources to very highly doped short-pulse amplifiers for 1.5 µm.
Our high concentration LIEKKI™ erbium fibers feature excellent efficiency due to low level of clustering. |
