Abstract

We report a novel method to accurately evaluate the impact of stretcher gratings on the contrast pedestal of high power laser pulses by precise quantitative characterization of the grating surface. The results are in a good agreement with the experimental measurement. We have, for the first time, established a relation between the contrast pedestal and natural property of stretcher gratings.
