Yb:YAG - Crystal

Description

Ytterbium-doped Yttrium Aluminum Garnet (Yb:YAG) is an important laser crystal for high-power diode-pumped solid-state lasers. Compared to the traditional Nd-doped laser materials, Yb:YAG crystals are more suitable for diode pumping. Yb:YAG crystals typically have a broader absorption bandwidth than Nd crystals, which allows for more efficient laser pumping and reduces the thermal management requirements. Additionally, the long lifetime of the Yb ion in the excited state allows for efficient energy storage and low heat generation. These properties make Yb an excellent material for high-power and high-efficiency laser systems. Shape Optics provides a variety of Yb:YAG crystals in different sizes and shapes, including rods, plates, and discs.
