Ytterbium doped yttrium aluminum garnet (Yb:_Y3Al5O12 or Yb:YAG) is one of the most promising laser active materials and is better for diode pumping than the traditional Nd:YAG crystals. It can generate 1.03µm laser radiation by pumping at 640nm. The main advantages of Yb:YAG are: Wide absorption bandwidth, high output powers and excellent emission. The Yb:YAG laser material is often used for industrial lasers for cutting and welding. The crystal can also be used in electronics, optics and laser technologies.
