Ytterbium-doped yttrium aluminum garnet
Material
Yb:YAG
Ytterbium doped Yttrium Aluminium Garnet (Yb:Y3Al5O12 or Yb:YAG) is a laser-active material that can be
By pumping with a wavelength of 640 nm, laser radiation with a wavelength of 1030 nm can be generated. The advantages of Yb:YAG are a wide absorption bandwidth, high output power, and high emission power.
The Yb:YAG laser material is often used for industrial lasers for cutting and welding. Likewise, the crystal can be used in electronics and for optical components.
