Abstract

Using a commercial picosecond laser system, experiments were performed to cleanly machine non-metals and measure material removal rates. The laser was operated at 532 and 355 nm using a unique pulse format and a galvo scanner to translate the beam. The test materials include quartz, sapphire, alumina ceramic, polytetrafluoroethylene (Teflon®) and silicon. The material removal is reported as both a depth per pass of the beam at a particular speed, and also a volumetric removal as a function of time. Scanning electron microscope pictures reveal the laser parameters that leave the sharpest edges, with minimal melt and debris.
