High Power CO2 Laser Windows and Reflection Reducing Coatings,

Abstract

This article describes evaluation standards for window materials. In conjunction with that, comparisons were made between the four types of materials Ge, GaAs, ZnSe, and KCl. It was discovered that KCl possesses optimum optical characteristics. In conjunction with this, reflection reducing films associated with good performance were designed and prepared. Measurements were done of their absorption and laser damage threshold values. (AN)
