Radial polarization converter S-waveplate is the most common available space-variant waveplate. Higher order s-waveplate is similar to ordinary – converts linear polarization to radial or azimuthal polarization. However, this product can generate higher topological charge optical vortices.
Fabrication of higher order S-waveplate is based on the inscription of self-organized nanogratings inside fused silica glass using a femtosecond laser.
Referring to LIDT measurements at fs regime (full report) and ns regime (full report), we’ve observed our s-waveplates has laser irradiation resistance similar to uncoated fused silica substrates.
LIDT value measured at 1064 nm, ~10ns is 63,4 J/cm2 and it is not dropping while increasing exposure time. It proves, our waveplates are very high performance and suitable for high power laser applications.

Optical Vortex Generation Using Radial Polarization Converter
Following step-by-step procedures must be done in order to generate an optical vortex beam using a radial converter.
Simplified approach:
Note: The sign of the optical vortex charge „+“, „-“ is controlled by the handedness of the incident circular polarization.
