Abstract:

A dielectric mirror with high reflectance at a wavelength of 266 nm has been designed for use in ultraviolet lidar systems for ozone concentration monitoring. A multilayer interference coating based on HfO₂ and SiO₂ was manufactured and optimized using experimentally obtained dispersion data. The effect of thermal annealing on the optical properties of the coating was investigated, and a temperature limit was identified, excess of which leads to structural degradation. The results can be used in the design of highly efficient optical elements for ultraviolet differential absorption lidars, as well as other laser systems which require UV dielectric mirrors.

Keywords:

dielectric mirror, ion beam spultering, UV coating, ozone lidar, interference coating
