<title>Holographic transformation between optical beams with spherical and cylindrical wave fronts</title>

Abstract

Cy1indricaI optical elements play iixiportant role in processing diode laser beams. Alternatively, diffractive elements can be used especially if they are simply holographically recorded. Analysis of the holographic recording process of elements trausforxniiig beams with spherical wave fronts into beanis with cylindrical wave fronts is presented. Only rotationally symmetric beams can be used for recording. Four equations provide four unknown parameters. Two examples were realized: one for transformation of a divergent beam with a spherical wave front into a cylindrical divergent beam with a cylindrical wave front the focal line of which lies in the meridional plane and the other for transformation of a collimated beam into a convergent beam with a cylindrical wave front with the same property of the focal line.
