It is shown that, to optimize the beam-quality parameter, the phases of the two Cartesian components of the field at the output of the APP plate should, be identical and should exhibit a quadratic dependence on the radial polar coordinate.engjournal articlehttp://dx.doi.org/10.1364/JOSAA.20.000577http://www.opticsinfobase.orgopen access535Parametric CharacterizationOptical-SystemsMatrixLawsÓptica (Física)2209.19 Óptica Física
