LIEKKI TM Er60-20/125 and Er60-40/250 fibers are large mode area erbium doped fibers suitable for medium power amplifiers and lasers. These fibers are ideally suited for compact, eye-safe devices (1.55 - 1.6 μm region). Both 980 nm and 1480 nm pump diodes may be used for pump sources.
LIEKKI TM Er60-xx/xxx fibers are currently only available as double cladding (Er60-20/125DC and Er60- 40/250DC) fibers.
Features
・Good beam quality through low numerical aperture core
・Good efficiency
・Suitable for both 980 nm and 1480 nm pumping
・Pump combiner available for the 20/125 geometry
