Abstract
Methods related to efficient processing of sapphire are discussed which are expected to both speed manufacture of corundum for applications and make the use of conundrum cost effective. In particular, one embodiment may take the form of a method of cutting a hard transparent material having a polished surface. The method includes roughening the polished surface, directing a laser beam at the hard transparent material to melt the material and removing the melted hard material.
