Abstract: A system and method of forming a sapphire component. The method may include disposing an absorptive-barrier layer on a first surface of a sapphire substrate, performing a cut in the sapphire substrate using a laser beam incident on the absorptive-barrier layer, and forming and removing molten sapphire from the cut. The method may also include shielding a region of the first surface that is adjacent to the cut from the molten sapphire using the absorptive-barrier layer, and removing the absorptive-barrier layer from the first surface of the sapphire substrate.

Abstract: A system and a method for manufacturing a sapphire part. A sapphire substrate is obtained for performing a laser cutting operation. The sapphire substrate is cut along a cut profile using a laser and a first gas medium. The first gas medium is substantially comprised of an inert gas. The sapphire substrate is then irradiated at or near the cut profile using the laser and a second gas medium. The second gas medium is different than the first gas medium comprising oxygen.

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.
Abstract translation: 讨论了与蓝宝石有效处理有关的方法，其预期将用于快速制造用于应用的刚玉并且使得难以实现成本效益。 特别地，一个实施例可以采取切割具有抛光表面的硬质透明材料的方法的形式。 该方法包括使抛光表面粗糙化，将激光束导向硬透明材料以熔化材料并除去熔融的硬质材料。
