Erbium Doped Yttrium Aluminum Garnet (Er:YAG) is a unique and versatile material used extensively in industrial applications. Its primary use is in the field of laser technology, where it serves as an active laser medium. The Er:YAG laser is renowned for its remarkable proficiency in emitting light at a wavelength of 2940 nm, which is highly absorbed by water. This characteristic makes it particularly useful in medical applications, such as in dermatology for skin resurfacing and in dentistry for precise, minimally invasive procedures. Its wavelength is also ideal for cutting and welding certain materials, making it valuable in manufacturing and precision engineering. Additionally, Er:YAG lasers are employed in the telecommunications industry for fiber optic communication systems, where they enhance signal strength and quality. The versatility and efficiency of Er:YAG make it a critical component in the advancement of various high-technology fields.

This material was grown in the old Soviet Union via the HDSM method.
