ABSTRACT:
The conversion of linear polarized light into radial-polarized light is accomplished through a radial polarization generator containing multiple layers of polarizing film, or polarization converters, for converting the beam of light to a different orientation. Using the radial polarization generator, a quasi radial-polarized beam of light can be obtained quickly and easily by simply aligning the light at the center of the polarization generator. True radial-polarization can be obtained by passing the laser through a spatial filter. With such a radial polarization generator, a large frequency range of light may be converted from a linear orientation to a radial orientation.
