A thin-film plate 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 HfO{sub 2}/SiO{sub 2} 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.
