title: Design of ultrahigh energy laser amplifier system with high storage energy extraction.
abstract: A design concept of realizing high storage energy extraction efficiency is presented for an ultrahigh energy laser system, stressing the advantage of variable-diameter aperture structure for the multistage amplifier system over the constant-aperture design. Based on the established modeling, the conceptual schematic of an amplifier system with optimized high storage energy extraction is developed, which is expected to produce 15 kJ output energy from three stages, with an extremely high storage extraction efficiency of 50.3%.
