Abstract

In this paper we address the transient temperature distribution and subsequent optical distortion resulting from an annular high power continuous wave laser beam on to coated, non-cooled optical components. The transient temperature distribution is described using The Reverse Thermal Wave Transform. The optical components are uncooled and subject to thermal shock. The standard equations are used for evaluating thermal shock as a function of time, coating expansion coefficient, and material for both substrate and coatings.
