Drawings are given for the Shiva spatial filters, which are lens-pinhole-lens combinations designed to remove spatial intensity ripples from a laser beam and produce a smooth beam profile. The filter functions by focusing the beam through a diamond pinhole where the intensity ripples (which cannot focus through the pinhole) are removed. Several spatial filters of different sizes are distributed along the laser chain in order to remove the ripples before they grow to intolerable intensity. The diamond pinhole is mounted in a vacuum chamber to prevent the formation of an opaque plasma near the focus.
