Large-Mode-Area (LMA) Matching Passive Fibers
Thorlabs offers a range of passive large-
mode-area (LMA) fibers matched with
available active LMA fibers such as Liekki’s
YB1200 product family. These passive fibers
are matched to the core diameters and
numerical apertures of their active
counterparts to maintain excellent beam
quality throughout fiber laser or amplifier
systems. The outer cladding diameter is
designed to “round” the shaped active fibers
in order to achieve a low coupling loss when
matching passive to active fibers. The passive
fibers are coated with low-index
fluoroacrylate, enabling active fibers to be
pumped through them. High-index acrylate
coated fibers are available by special request;
please contact us for details.

PM passive fibers are matched to the
core size and NA of their matching
active fibers.
Non-PM passive fibers are matched
to the core size and NA of their
matching active fibers and fit within
their octagonal cladding.
