Ytterbium-doped large mode area polarisation-maintaining fiber

YB-MCOF-35/250-07-2.5-PM

Description

Specifications

Yb-doped large mode area PM fiber

Developed by our key partner INO, the Yb-MCOF-35/250-07-2.5-PM fiber is designed for M 2 lower than 1.15 making it the perfect choice for applications requiring superior beam quality. It features a confined core for selective gain amplification and multi-layer cladding for superior suppression of higher order modes.
