Abstract

Optical coatings with very low absorption losses have been produced on silicon and fused silica in the 1 to 3 micron spectral region. Absorption values below 30 ppm have been achieved at oxygen-iodine and hydrogen fluoride laser wavelengths with fluence levels as high as 40 kW/cm². The optical performance of these coatings in producing ultra high reflectance mirrors (R equals 99.97%) and predicted performance, extrapolated from this data, for the deuterium fluoride laser wavelength region are presented. These results are critical in the production of optical components for application in high power, high fluence mid-infrared cw laser systems.
