Abstract

The results of our investigations on direct laser fabrication of micro spiral phase plates (SPPs) in fused silica using the fluorine laser microstructuring technique will be presented. The process, which based on the mask projection technique, enables the generation of SPPs with different topological charges, handedness, modulation depths and level numbers. For this, a special double mask rotation system was developed, which allows the fabrication of micro SPPs with an individual configuration with regard to the mentioned parameters. Moreover, the phase of a spherical lens can be added to the helical phase of the SPP using a special mask geometry. Furthermore, we build up a measurement system for a first optical characterization of the fabricated SPPs.
