Manufactured by NKT Photonics A/S, the DC-200-40-PZ-YB-03 is a
rare-earth-doped ytterbium fiber. The patented polarizing double-clad fiber with
coil control features a mode area of more than 650 μm2 while maintaining single-mode
beam quality. Because it is polarizing, it delivers an improved polarization extinction
ratio compared with polarization-maintaining fibers, according to the company. The
multimode pump light is guided by proprietary air-clad technology, ensuring low
loss, a high damage threshold and a large numerical aperture that relaxes tolerances
on coupling optics and facilitates the use of lower brightness diodes. Used by industrial
fiber laser manufacturers, it is available with sealed ends or with end caps and
high-power SMA connectors in the company’s aeroGain Flex range.
