Abstract

The first known 10.6 micrometers wavelength mirrors entirely coated with the help of the dual- ion-beam sputtering deposition technique are presented. This new coating technology proved suitable for making good quality mirrors which can withstand severe civil and military standards such as climatic and temperature tests. Moreover, these mirrors exposed locally to a very high power density ($OM 100 kW/cm2 in cw mode) do not show any microdamage even after a long period of use. These up-to-date mirrors initially developed for military applications meet the requirement of high power cw CO2 lasers used for industrial applications.
