Abstract: A lithium aluminosilicate glass-based article includes greater than or equal to 55.0 mol % and less than or equal to 75.0 mol % SiO2, greater than or equal to 1.0 mol % and less than or equal to 18.0 mol % Al2O3, and greater than or equal to 9.0 mol % and less than or equal to 25.0 mol % Li2O. The glass-based article has a thickness less than 0.74 mm, a fracture toughness of the mid-plane composition of the glass-base article is greater than or equal to 0.75 MPα√{square root over (m)}, and a depth of compression that is greater than or equal to 0.14t, where t is the thickness of the glass-based article. The glass-based article is designed to have a single guided mode in the prism coupling spectrum at a wavelength between 360 nm and 405 nm for at least one of the transverse-magnetic or transverse-electric polarization.

Abstract: Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.

Abstract translation: 公开了形成玻璃制品的方法。 在一个实施例中，形成玻璃制品的方法包括将脉冲激光束平移在玻璃基板上，以在玻璃基板的第一表面和第二表面之间形成激光损伤区域。 该方法还包括将蚀刻剂溶液施加到玻璃基片上以除去玻璃基片周围激光损伤区的一部分。 该方法还可以包括通过离子交换强化工艺来加强玻璃基片，并且用耐酸性涂层涂覆玻璃基片。 还公开了这样的方法，其中激光损伤区域具有在玻璃基板的重整之后变为所需几何形状的初始几何形状，使得激光损伤区域的初始几何形状补偿玻璃基板的弯曲。
