摘要

Several fundamental restrictions limit the implementation of microlasers in high power systems, low resistivity of coatings and compactness of elements, especially if control of polarization is necessary. Thin-film-based coatings with extremely high optical resistivity and polarizing properties for normal incidence could become a preferable solution. In this Letter, a novel multilayer approach to form all-silica polarizing coatings for normal incidence angle applications is proposed. Laser induced damage thresholds (test one-on-one) at the wavelength of 355 nm were 39 J/cm(2) and 48.5 J/cm(2) for the reflected and transmitted polarizations, respectively. Such elements can essentially improve tolerated radiation power and allow for production of more compact laser systems. (C) 2021 Optical Society of America
