Abstract: New capabilities of an "optical boiler" pumping system, characterized by a high lasing efficiency and a high density of the stored energy, were predicted theoretically and confirmed experimentally. A record lasing efficiency of ~ 2.85% for single pulses was achieved in a pumping system with YAG:Nd rods distributed around a flashlamp when the output energy from one rod was 300 mJ. An increase in the efficiency in excess of 3% was forecast.
