Abstract
The purpose of these studies has been to understand the mechanisms involved in the coupling of 10.6 mu m laser radiation to metallic surfaces in air and vacuum. As differences were expected for CW (continuous wave) and pulsed excitation, experiments were carried out using both excitation modes. With pulsed excitation of surfaces one expects variations in coupling coefficient to occur when the laser power is high enough to promote surface breakdown. Thus care was taken to ensure that measurements were carried out over a range of laser intensity both above and below the threshold for surface breakdown. The report summarizes the data presented in the four previous progress reports and contains a discussion of new data obtained under the extended contract.
