<title>Measurement of optical coating LIDT vs. their ion milling deposition parameters</title>

Abstract

High LIDT (laser induced damage threshold) optical coating deposition techniques are of large practical interest for those who develop compact and high power pulsed lasers. Currently several technologies are used to deposit such coatings. But parameters and conditions of such technologies usually are not discussed in detail because of commercial reasons. Authors of this paper have developed efficient methods to find optimum conditions for high LIDT optical coatings deposition. This method is based on utilizing high precision and reproducibility LIDT measurement system and ion milling optical coating deposition system placed at the same laboratory for real time feedback.
