Yb:YAG - Ytterbium Doped Yttrium Aluminum Garnet
Yb:YAG is an important laser-active material.
Compared with Nd:YAG, Yb:YAG has a much larger absorption, a longer upper-laser level lifetime, 3 to 4 times lower thermal loading per unit pump power.
Compared with Nd:YAG, Yb:YAG has a much larger absorption, a longer upper-laser level lifetime, 3 to 4 times lower thermal loading per unit pump power.
Advantage:
Very low fractional heating, less than 11%
Very high slope efficiency
Broad absorption bands, about 8nm @940nm
No excited-state absorption or up-conversion
Conveniently pumped by reliable InGaAs diodes at 940 nm(or 970 nm)
High thermal conductivity and large mechanical strength
High optical quality
