Abstract

In this work, an all-dielectric light polarizing element with 0 angle of incidence was fabricated and investigated. Linear polarizer for 1064 nm wavelength was formed by conformal deposition of dielectric thin films on the structured substrate. Its potential in laser applications was tested with laser-induced damage threshold evaluation for single-shot nanosecond pulses. Despite only dielectric materials, the optical resistance of the periodically structured element is several times inferior to that of the planar element. Differences in optical resistance correlate with formed electric field peaks within the modulated structure, revealing the problem to be solved in the ongoing work.
