Paper Abstract

The work is a numerical and experimental study of closely spaced light spot production using diffractive optical elements (DOE). It is shown that low indexed Hermite–Gaussian mode formers coupled with an objective can be utilized for the production of contrasting closely spaced small light spots in objective focus. Using a tunable laser (EKSPLA NT 242), we demonstrate that low indexed mode forming is quite resistant to chromatic dispersion, but is extremely sensitive to shifting axes of the incident beam and the element.
