Passive pulse shapers including Fabry-Perot etalons, double-etalons, and classical beam splitters are examined both theoretically and experimentally for their temporal behavior. For temporally and spatially overlapped pulses, interpulse interference effects determine the resulting pulse shapes. The output pulses from such devices are expected to be of great importance for laser fusion pulse shaping.
