BrightCore’s Double-Clad Large Mode Area (LMA) Yb doped fibers are few-moded with a low NA

and large core diameter. They are optimally designed to lower the non-linearity and facilitate high

power laser output with high beam quality. Manufactured with a proprietary process and optimal

glass composition, these fibers offer superior laser conversion efficiency and photo-darkening

performance. All BrightCore double-clad fibers are made with improved low index coating and are

proof tested at 100kpsi level to ensure reliability, consistency and stability. They are widely used in

material processing, additive manufacturing, laser cleaning, scientific research and medical

applications.
