dc.description.abstract In this poster the authors discussed the ability to heat an industrial diamond sample by means of optical absorption of a CO2 laser beam, and then measure the resulting temperature on the surface of the diamond optically by means of radiometry principles. A model for the temperature on the surface of the diamond was developed and they show that it agrees qualitatively with experimental data. In particular, they show that it is possible to engineer the boundary conditions and initial beam such that uniform temperature gradients can be created, thus allowing the study of thermal effects in the absence of thermal stresses. They make use of the known grey body emission from polycrystalline diamond (PCD). They show that uniform temperature alone can account for significant structural changes in PCD diamond. en_US
