Materials and Process Characterization to Determine the Effect of High Intensity Infrared Laser Radiation on a Composite Material,

Abstract

Measurements were made of the true (black body) surface temperature of a well-characterized metal-doped carbon-carbon composite during irradiation with an intense, continuous-wave, CO2-laser beam along with spectrometric determination of the temporal variation of C2 and C3 species appearing in the laser-induced plume in a high vacuum environment. Various analytical methods used for post-burn analyses, during irradiation analyses, and material characterization are detailed. Thermodynamic aspects are considered. A synopsis of the stages in laser/beam/composite interaction derived from this study is included. Originator supplied keywords include: Laser target interactions, Endothermic reactions, Photochemical reactions, High surface temperature, and Emission spectroscopy.
