Paper Abstract
The optical performance of beam splitters developed for deuterium fluoride (DF) laser applications as shared- aperture components is presented. This component simultaneously has provided high reflectance in 3.8 micrometers DF laser output band and high transmittance in the visible wavelength region. The coating consists of a number of periods of multilayer stack which is reflecting in the infrared and transmitting at visible wavelengths. The period is formed of alternate high index ZnS and low index YbF3 materials layers which are transparent in the infrared and visible wavelengths. The 99.2% reflectance at 3.8 micrometers DF laser output band and 75.0% transmittance at 0.4 approximately 0.9 micrometers visible band have been obtained. The laser damaged threshold is more than 20 kw/cm2 at DF CW laser illumination.
