Abstract
Using a master oscillator-power amplifier (MOPA) configuration, 100J has been obtained from a 5 k optical volume KrF amplifier pumped at 300 kW/cm3 peak at the end of a 500 nsec pulse. A normalized input flux of 0.4 (I/Isat) was required to reduce amplified spontaneous emission (ASE) to one half the free running value. A peak extraction efficiency of 0.46 was obtained under these conditions at 1 atm total pressure. A kinetics model has been developed and refined to give excellent agreement with high and low pump regimes. An integrated kinetics and pulse propagation code has also been developed and agrees well with experiment.
