Yb:KGW crystals «In Stock»
Yb3+:KGW crystals possess a large gain bandwidth that enables them to obtain <100 fs pulse duration in the mode-locked regime of operation. Compared with other ytterbium-doped gain media with a similarly large gain bandwidth, ytterbium-doped tungstate has fairly high emission cross-sections. The ytterbium doping concentration in Yb:KGW crystals can be up to 5 at. % without a significant quenching. Thermal conductivity of common double tungstates is in the range of 3–4 Wm-1K-1. Yb:KGW crystals exhibit a small quantum defect and it is possible to operate with a quantum defect well below ~4-5%.
