Abstract:
A method of producing a substantially collimated beam of electromagnetic energy having substantially the same selected predetermined orientation of a chosen component of electromagnetic wave field vector and a substantially uniform flux intensity substantially across the beam of electromagnetic energy, comprising:[a] providing a substantially collimated beam of electromagnetic energy having a predetermined range of wavelengths; [b] resolving from the substantially collimated beam of electromagnetic energy a substantially collimated first resolved beam of electromagnetic energy having a first selected predetermined orientation of a chosen component of the electromagnetic wave field vector and a substantially collimated second resolved beam of electromagnetic energy having substantially a second selected predetermined orientation of a chosen component of the electromagnetic wave field vectors, whereby the first and second selected predetermined orientation of the chosen component of the electromagnetic wave field vectors are different from each another; and [c] forming from the substantially collimated first resolved beam of electromagnetic energy and the substantially collimated second resolved beam of electromagnetic energy a substantially collimated single beam of electromagnetic energy having substantially the same selected predetermined orientation of a chosen component of electromagnetic wave field vectors substantially across the substantially collimated single beam of electromagnetic energy and a substantially uniform flux intensity substantially across the substantially collimated single beam of electromagnetic energy.
