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.

Wuhan Brightcore Special Optical Fiber Co., Ltd. is located in "Wuhan · Optics Valley of China" and was established in October 2013. It is a professional manufacturer engaged in the research, development, production, and sales of special optical fibers.
The company possesses an internationally first-class industrial R&D laboratory and intelligent production lines. It has successively undertaken research projects such as the Hubei Major Science and Technology Innovation Program and the National Key R&D Program. It was the first in China to achieve the industrialization of double-clad large-mode-area ytterbium-doped fibers for lasers, holding a leading position domestically and an advanced position internationally. With the technical strength to replace imports, it has realized the independent control of key core materials in China's fiber laser industry chain.
The company has passed ISO certification and established a comprehensive quality, environmental, and occupational health and safety management system. As a key raw material supplier for the domestic fiber laser industry, it provides special optical fiber products that can replace imports and have strategic value, leading the development and innovation of special optical fibers for fiber lasers in China.
