Paper Abstract

The performance of the Beamlet laser with one dimensional smoothing by spectral dispersion implemented is investigated. Measurements of then ear field beam quality, nonlinear breakup, and transmission through spatial filter pinholes show a modest effect only at large SSD divergence. No measurable effect was found at the divergence level planned for indirect drive ignition experiments. The efficiency of conversion to the third harmonic was also measured with SSD present and found to be somewhat larger than expected form an ideal plane wave model.
