Abstract

Phase plates have been used in holography and laser fusion to produce a well-defined far-field intensity envelope that is relatively independent of the input-beam profile. However, superposed on this envelope is unwanted, highly modulated speckle from the interference between different phase-plate elements. We have developed a technique for choosing the phase-plate elements (in combination with polarization rotation) such that these intensity fluctuations approach zero in the limit of plane-wave near-field irradiation. Strategies are discussed for reducing the sensitivity of these zero-correlation phase masks to phase aberrations and other near-field imperfections, with particular emphasis on laser-fusion applications.
