Chromium, Thulium, and Holmium-doped Yttrium Aluminum Garnet (Cr,Tm,Ho:YAG) is a specialized material primarily used in industrial and medical laser applications. This triply-doped YAG crystal is notable for its efficient laser emission in the mid-infrared range, typically at a wavelength of 2.1 microns. This wavelength is particularly well-absorbed by water and biological tissues, making Cr,Tm,Ho:YAG lasers highly suitable for medical procedures, including minimally invasive surgeries and precision cutting in soft tissues. In industrial applications, these lasers are valued for their ability to process a variety of materials, especially those that require delicate and precise thermal management. They are often used in micromachining, where their specific wavelength allows for accurate and controlled cutting, drilling, and engraving of materials. The unique properties of Cr,Tm,Ho:YAG lasers make them a vital tool in both advanced manufacturing and medical technology sectors.
