Er:Yb:YAB Crystal (Erbium-Ytterbium Co-Doped Yttrium Aluminum Borate) is a top-tier material for 1550 nm laser applications, known for its high thermal conductivity and efficient Yb3+/Er3+ energy conversion. It provides high-power, high-efficiency continuous laser output at 1530 nm, outperforming Er3+/Yb3+ co-doped phosphide glasses. The 1550 nm laser, with its strong penetration through smoke and high atmospheric transparency, is perfect for LiDAR, 3D imaging, and target recognition. Its low up-conversion losses make it a preferred material for applications requiring reliable and powerful laser performance.
