Description
CTH:YAG Crystal is an advanced solid-state laser medium renowned for its ability to generate laser emissions at 2100 nm. This crystal is a composite material, doped with Chromium (Cr3+), Thulium (Tm3+), and Holmium (Ho3+), which makes it highly efficient for a variety of demanding applications. The unique triple-doping process enhances the crystal's performance, making it a preferred choice in fields such as medical, meteorological, and military sectors.
The CTH:YAG Crystal is crafted to ensure optimal spectral overlap of pump radiation, whether using a lamp or diode, with the absorption bands of Cr3+ and Tm3+. This characteristic, combined with a highly efficient conversion into the Ho3+ emission band, results in laser architectures that boast high quantum efficiency. This efficiency is critical for developing advanced laser systems that require precise and reliable performance.
In terms of its physical and optical properties, the host material formula for the CTH:YAG Crystal is Y3Al5O12, with a cubic structure. The crystal's refractive index at 2100 nm is 1.8, and it has a Mohs hardness of 8.5, indicating its robustness and durability. The product specifications are meticulously engineered, featuring precise dimension tolerances and high-quality surface finishes to ensure optimal performance in its applications.
