Er and Yb Co-Doped Fiber

Er and Yb Co-Doped Fiber is mainly used in high-power telecommunications/CATV fiber amplifiers, laser ranging, LiDAR, and human eye safety lasers. This fiber has low fusion loss and high optical to optical conversion efficiency. A higher absorption coefficient ensures output power and lower cost. Based on the mature preparation process, optical fibers can regulate the absorption coefficient and gain spectrum, with good consistency.
