Paper Abstract

A thin-film polarizer with a high polarization ratio for single laser wavelengths can be realized if a Fabry-Perot filter design is used.THe spectral width of the polarization region of the filter polarizer is smaller than that of the usual long-wave pass filter, but there are not the practical difficulties of depositing multilayer systems with a large number of layers having non-quarter-wave thicknesses. Experimental results of a HfO2/SiO2 Fabry-Perot filter polarizer at 355 nm are presented. The laser-induced damage thresholds of the polarizer are enhanced by minimizing E-field intensities and minimizing absorption.
