用坩埚下降法生长了Yb：PbF（2）和Yb，Na：PbF（2）激光晶体。研究了Yb（3+）离子在晶体中的室温吸收、光致发光光谱和荧光寿命。实验结果表明，Na+与Yb（3+）共掺杂作为电荷补偿剂，可以抑制Yb（3+）还原为Yb（2+）。本文报道了Yb，Na：PbF（2）单晶在二极管泵浦下的激光运转结果。以1mol.% Yb（3+）掺杂样品在978nm入射功率为17.9W时，获得了2.37W的1056nm激光输出。
Yb:PbF(2) and Yb,Na:PbF(2) laser crystals are grown by the Bridgman method. Room-temperature absorption, photoluminescence spectra, and fluorescence lifetimes of Yb(3+) ions in the crystals have been investigated. Experimental results show that Na(+) ions codoping with Yb(3+) as charge compensators can suppress the deoxidization of Yb(3+) to Yb(2+). The result of diode-pumped laser operation of a Yb,Na:PbF(2) single crystal is reported for the first time to the best of our knowledge . With a 1mol.%Yb(3+)-doped sample, we obtained 2.37W output power at 1056nm for 17.9W of incident power at 978nm.
