Theoretical investigation is made of the possibility of constructing a high-power neodymium-glass laser in which diverging light beams are amplified in conical rods and funnel-shaped disks. A theoretical model is developed for the amplification of diverging beams. This model is applied to calculations of the parameters of amplified pulses and of neodymium-glass active elements.
