Higher Order S-Waveplate Polarization Converter
Higher-order S-waveplate converts linear polarization to higher-order polarization patterns.
The fabrication of s-waveplates is based on the inscription of self-organized nanograting’s inside fused silica glass using a femtosecond laser.
LIDT measurements at fs regime (full report) and ns regime (full report) show our S-waveplates have laser irradiation resistance similar to uncoated fused silica substrates. LIDT value measured at 1064 nm, ~10 ns 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.
