摘要：

We describe the efficient operation of a Nd:KGd(WO4)(2) laser at 1.067 mu m pumped by Ti:sapphire and diode lasers. Preliminary data indicate a relatively low threshold and high efficiency for a 10 mm diameter X 10 mm long antireflection-coated crystal. The wide high-absorption band was centered near 810 nm. The fluorescence lifetime was 109 mu s, and the stimulated-emission cross section was approximately 3.5 X 10(-19) cm(2). Slope efficiencies of 43% and 44% were attained for diode laser and Ti:sapphire pump sources, respectively.
