Efficient continuous-wave lasing operation of Nd:KGd(WO(4))(2) at 1.067 microm with diode and Ti:sapphire laser...

We describe the efficient operation of a Nd:KGd(WO(4))(2) laser at 1.067 microm 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 micros, 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.
