    Abstract: A method of modifying the CTE of a glass body is described, the method including determining a spatial CTE distribution of a ULE glass body including SiO2 in a range from about 80 wt. % to about 99 wt. % and TiO2 in a range from about 4 wt. % to about 11 wt. %, the glass body further including at least a first region and a second region, and directing a pulsed laser beam to at least one of the first region or the second region to modify at least one of a first CTE of the first region or a second CTE of the second region.

    Abstract: Strengthened glass articles having laser etched features, electronic devices, and methods of fabricating etched features in strengthened glass articles are disclosed. In one embodiment, a strengthened glass article includes a first strengthened surface layer and a second strengthened surface layer under a compressive stress and extending from a first surface and a second surface, respectively, of the strengthened glass article to a depth of layer, and a central region between the first strengthened surface layer and the second strengthened surface layer that is under tensile stress. The strengthened glass article further includes at least one etched feature formed by laser ablation within the first surface or the second surface having a depth that is less than the depth of layer and a surface roughness that is greater than a surface roughness of the first surface or second surface outside of the at least one etched feature.

    Abstract: Apparatus can comprise a light source and a light guide plate. The light guide plate can comprise a plurality of features within an interior of the light guide plate. A feature of the plurality of features can comprise a first refractive index that is different from a refractive index of the light guide plate. A spacing between a pair of adjacent features of the plurality of features can be from about 20 micrometers to about 200 micrometers. The apparatus can be used to direct light out of the light guide plate with a peak radiance oriented from 0° to 30° from a direction normal to the first major surface of the light guide plate. Methods of making the apparatus can comprise emitting a burst of pulses from a laser. Methods can comprise focusing the burst of pulses into a line focus within the light guide plate.
