The Yb-MCOF-35/250-05-2.0-PM is a multi-clad, PM fiber with a low numerical aperture singel-mode core having a diameter of 35 µm, designed for M² lower than 1.15. Our fiber features a confined core for selective gain amplification and multi-layer cladding for superior suppression of higher order modes, making it perfectly suited for amplifying narrow linewidth seed lasers operated in pulsed mode and for applications requiring superior beam quality.
