Abstract

A study to examine beam-solid interaction as a function of the cut surfaces of pyrolytic graphite samples (0, 30, 60, and 90 degrees relative to the basal plane) was made using a high intensity, carbon dioxide laser beam operating at a wavelength of 10.6 μm.

Crystal growth of redeposited carbon and impurities in the burn area as well as a melt on the burn edge were observed and examined using Scanning Electron (SEM) and Scanning Auger Microscopy (SAM). Similarities and differences relating to the structure of the material were further investigated using X-ray diffraction. Thermal transport properties as a function of angle were also examined.
