Paper Abstract

In this paper we describe the fabrication of reflective spiral phase plates with a deposition system. This plate was used to transform Gaussian beams into Laguerre-Gauss beams with angular momentum. These beams are characterized by a helical wave front and zero intensity at center. By focusing a femtosecond Laguerre-Gauss beam with an axicon, we have produced surface modifications in a BK7 glass sample.
