    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 colored sapphire material and methods for coloring sapphire material using lasers are disclosed. The method for coloring the sapphire material may include positioning the sapphire material over an opaque substrate material, exposing the opaque substrate material to a laser beam passing through the sapphire material to impact the substrate material, and inducing a chemical change in a portion of the sapphire material exposed to the laser beam. The method may also include creating a visible color in the portion of the sapphire material as a result of the chemical change. The colored sapphire material may include a first transparent portion, and a second, colored portion substantially surrounded by the first portion. The second, colored portion may have a chemical composition different than that of the first portion.

    Abstract: A ceramic material, such as sapphire, is irradiated using a laser-based process to form a cut. In some implementations, a region of the ceramic material adjacent to the cut may be heated. The region may be removed to form an edge feature. In various implementations, the region of the ceramic material adjacent to the cut may be shielded from an outer portion of a laser beam used in the laser-based process using a shield, such as a polyethylene film. This removal and/or shielding operations may improve the mechanical strength of the ceramic material.

    Abstract: Anodized substrates having laser markings and methods for forming the same are described. According to some embodiments, the methods involve forming a feature on a substrate using a laser prior to anodizing. The laser energy and pulse width can be chosen so as to provide a particular topology to a surface of the substrate that, after anodizing, absorbs incoming light and imparts a dark appearance to the feature. In some cases, the methods involve forming a coarse oxide layer, which is removed prior to anodizing. Since the laser marking is performed prior to anodizing, the anodized substrates are free from laser-induced cracks, thereby making the anodized substrates more corrosion resistant than conventional laser-marked anodized substrates. The techniques are well suited for forming features on consumer products that may be exposed to water or other corrosion-inducing agents.
