Yb: KGW Description
Yb:KGW stands for Ytterbium-doped Potassium-Gadolinium Tungstate. It is a type of laser crystal doped with Ytterbium (Yb) ions. Yb:KGW crystals serve as the gain medium in solid-state lasers.
Yb:KGW crystals are valued for their ability to produce laser light in both the near-infrared (NIR) and infrared (IR) regions of the electromagnetic spectrum. They are used in various fields, including industry and materials processing, scientific research and in medicine.
