摘要：An apparatus for producing an inhomogeneously polarized optical beam from a

homogeneously polarized input optical beam includes a first phase shifter, a secondphase shifter, and one or more polarization beam splitters. The first phase shifter shiftsat least one portion of a first part of the input optical beam by a first phase. The secondphase shifter shifts at least one portion of a second part of the input optical beam bysubstantially the first phase. The one or more polarization beam splitters split the inputoptical beam into the first part and the second part and combine the phase shiftedportion and substantially all other portions of the first part of the input optical beamwith the phase shifted portion and substantially all other portions of the second part ofthe input optical beam to produce the inhomogeneously polarized optical beam.
