Product Description

Ho:YAG Crystal

Ho:YAG (Holmium-doped Yttrium Aluminum Garnet) crystals emit radiation at a wavelength of 2090 nm, which lies in the eye-safe region of the spectrum and has high atmospheric transmission. This makes Ho:YAG crystals highly valuable for applications in remote sensing, laser ranging, and lidar. Additionally, the 2090 nm wavelength corresponds to the absorption peak of water molecules in human tissue, making it ideal for medical procedures. The penetration depth of Ho lasers in human tissue is only a few tens of micrometers, minimizing thermal damage to surrounding tissues. As a result, Ho lasers are widely used in medical surgeries and treatments. Furthermore, Ho lasers can serve as a pump source for generating mid-infrared lasers in the 3-5 mm range through the nonlinear effects of crystals like ZGP.
