Yb:YAG (Ytterbium Doped Yttrium Aluminum Garne ) crystal is one of the most promising laser-active materials and more suitable for diode-pumping then thetraditional Nd doped systems. It can be pumped at 0.94um laser output.
Compared with the commonly used Nd:YAG crystal. Yb:YAG (Ytterbium Doped Yttrium Aluminum Garne ) crystal has a much larger absorption bandwidth to reduces thermal management requirements for diode lasers, a longer upper-state lifetime, three to four times lower thermal loading per unit pump power.
Yb:YAG (Ytterbium Doped Yttrium Aluminum Garne ) crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other potential applications.
Yb:YAG shows great promise as a high power laser material.
Several applications are being developed in the field of industrial lasers, such as metal cutting and welding.
With high quality Yb:YAG now available, additional fields and applications are being explored.
