Fiber laser
A
fiber laser
or
fibre laser
is a
laser
in which the
active gain medium
is an
optical fiber
doped with
rare-earth elements
such as
erbium
,
ytterbium
,
neodymium
,
dysprosium
,
praseodymium
, and
thulium
. They are related to
doped fiber amplifiers
, which provide light amplification without
lasing
. Fiber
nonlinearities
, such as
stimulated Raman scattering
or
four-wave mixing
can also provide gain and thus serve as gain media for a fiber laser.
