Yb:YAB Crystal | Ytterbium-Doped Yttrium Aluminum Borate Crystal

Yb:YAB Crystal (Ytterbium-Doped Yttrium Aluminum Borate) is a unique multifunctional material known for its outstanding mechanical strength, high thermal conductivity, and stable chemical properties. As a negative biaxial crystal, it possesses nonlinear optical characteristics, enabling efficient infrared-to-visible light conversion via second-order nonlinear processes. The crystal can incorporate high concentrations of Yb3+ ions with minimal concentration quenching, making it ideal for high-performance laser applications. Yb:YAB Crystal is widely used in laser systems, optical communication, and other advanced technologies. Heeger Materials provides high-quality Yb:YAB Crystals for demanding applications.
