Paper Abstract

Effects of the single and multispatial filter (SF) on the light field in the ICF laser drive have been studied in detail. It has been found that the low spatial frequency rings and ripples in the intensity distribution of the output light field depend only on the ratio of filtering pinhole size to the diffraction-limit of the input beam. The modulation-depth, focal-depth and filling-factor of the laser beam passing through a SF have also been investigated. For the multi-spatial filter, there exists, in the frequency-domain, a simple and analytical relationship between the input and output frequency spectrum under a special case, and among the filtering pinholes there is a most effective one that performs as if the other filtering apertures can be disregarded.
