Details

Yb:YAG crystals are more suitable for diode-pumping than the traditional Nd-doped systems. It can be pumped at 940 nm laser output. Compared with the commonly used Nd:YAG crystal, Yb:YAG crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-state 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.

Ideal for diode pumping;
Very low fractional heating, less than < 11%
Very high slope efficiency, more than 56%
Broad absorption bands, about 18nm @ 940nm
High thermal conductivity and strength
