Paper Abstract

The characteristics of the 3(omega) focal spot are determined by the properties of the 1(omega) beam and the frequency tripling process. The size of the 3(omega) focal spot depends on the spectrum of spatial noise in the 1(omega) beam. A perturbation theory for ripple transfer in frequency tripling is used to predict the characteristics of the 3(omega) focal spot. The theory predicts that 1(omega) phase noise grows 9X in power in the tripling process. This can cause a significant reduction in 3(omega) energy delivered to the target. Results from Beamlet 3(omega) focal spot characterization experiments are also presented.
