ERBIUM FIBERS
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.

LIEKKI? erbium fibers are available in the following fiber types
1) Single mode and large mode area (LMA)
2) Single, double and triple cladding
