Tm,Ho:KYW Crystals, Right-angle cut
We offer Tm,Ho:KYW Crystals in various specifications. Co-doping of Ho3+ with Tm3+ is for efficient operation in the 2 μm region via an energy transfer path from Tm3+ to Ho3+. Tm,Ho:KYW crystals are characterized by large and broad polarized absorption and emission bands for efficient energy transfer from Tm3+ to Ho3+.
