A split-disk geometry amplifier is reported, which uses several highly doped thin phosphate glasses instead of a single thick plate in such an ordinary disk amplifier to improve cooling efficiency. A simulation code was developed for the potential extrapolation of the experimental results under more severe pumping conditions to design the specifications of electrical parameters, disk glass thickness, Nd doping rate, and pumping cavity geometry and also to evaluate the gain coefficient of the amplifier. A gain coefficient of 0.027 cm<SUP>-1</SUP> calculated in active media volume of 300 cm<SUP>3</SUP> with a pumping efficiency of 0.92 % at 4 kJ pump energy agrees with the experimental value within errors of less than 10 %.
