Yb:YAG is one of the most promising laser-active materials and more suitable for diode-pumping than the traditional
Nd-doped systems. Compared with the commonly used Nd:YAG crsytal,Yb:YAG crystal has a much larger absorption
bandwidth to reduce thermal management requirements for diode lasers, a longer upper-laser level lifetime, three to
four times lower thermal loading per unit pump power. Yb:YAG crystal is expected to replace Nd:YAG crystal for high
power diode-pumped lasers and other potential applications.
