In this paper, we consider a technique which is both diffractive and interferometric for converting a linearly polarized TEM laser beam into a radially polarized beam with uniform azimuthal intensity distribution. The basic idea is to achieve the coherent summation of two orthogonally polarized Hermite-Gaussian TEM and TEM beams by using a vectorial Mach-Zehnder interferometer. The beam transformation TEM/sub 00//spl rarr/TEM/sub 10/ and TEM/sub 00//spl rarr/TEM/sub 01/ is achieved in each interferometer arm by using a simple diffractive optical element which is referred as a phase step which is made of a transparent glass on which a thin polymer film is deposited.
