Yb:KYW Crystals, 10%Doping, Right-angle cut, 5mm*5mm
Yb3+:KYW crystals have large gain bandwidths and fairly high emission cross sections. The ytterbium doping concentration in Yb:KYW crystals can be very high without significant quenching. Yb:KYW crystals also have small quantum defects. We can provide Yb3+:KYW crystals with different specifications.
