Abstract

We describe the efficient operation of a Nd:KGd(WO4)2 laser at 1.067 μm pumped by Ti:sapphire and diode lasers. Preliminary data indicate a relatively low threshold and high efficiency for a 10 mm diameter × 10 mm long antireflection-coated crystal. The wide high-absorption band was centered near 810 nm. The fluorescence lifetime was 109 μs, and the stimulated-emission cross section was approximately 3.5 × 10−19 cm2. Slope efficiencies of 43% and 44% were attained for diode laser and Ti:sapphire pump sources, respectively.
