Abstract
A temperature field simulation study of CVD diamonds under nanosecond laser processing was carried out to investigate the characteristics of diamond graphitization and material removal mechanisms during nanosecond laser processing. Experimental results show that diamond undergoes significant burn and graphitization during laser processing. The graphite layer thickness and width of the diamond surface were measured to determine the regularity of nanosecond laser-induced diamond graphitization. Analysis of the simulation results for the diamond temperature profile shows that the nanosecond laser irradiation energy is mainly distributed over the diamond surface, and the thermal effect zone of nanosecond laser irradiation on the diamond is small, resulting in a graphite layer thickness of about 3.25 μm.
