Science, Technology and Mission Design for the Laser Astrometric Test Of Relativity
II we describe how such a wave may be created by use of a mode converter that basically consists of a parabolic mirror and optical elements which tailor the spatial and temporal distribution of the light field incident on to the parabolic mirror.
Design of a mode converter for efficient light-atom coupling in free space
The presence of the surface of the parabolic mirror might be expected to result in disturbing effects similar to the ones observed in the case of emitters that are positioned close to surfaces within a near field distance (see, e.g., Ref. and ci tations therein).
Design of a mode converter for efficient light-atom coupling in free space
Since the distance of the atom/ion to the mirror surface in case of a realistic parabolic mirror is much larger than a wavelength, near field effects do not play a role [27, 28 ].
Design of a mode converter for efficient light-atom coupling in free space
This main optical element may be a reflecting telescope with a single parabolic mirror, or one with two or more mirrors; it may be a refracting telescope using dielectric lenses; it may be an array of mirrors configured as an interferometer; it may be just a horn antenna 2 .
