KrF laser fusion: Perform optical systems study of direct short pulse extraction
Abstract
The performance of KrF in a regime of inertial confinement fusion was determined both experimentally and analytically. Using a master oscillator power amplifier configuration, 100J was obtained from a 5 optical volume KrF amplifier pumped at 300 KW/cu cm peak at the end of a 500 nsec pulse. A normalized input flux of 0.4 was required to reduce amplified spontaneous emission to one half of the free running value. A peak extraction efficiency of 0.46 was obtained under these conditions at 1 atm total pressure. The kinetics model was refined in agreement with high and low pump regimes and an integrated kinetics and pulse propagation code was developed.
