    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: A method of joining glass substrates is disclosed. The method positions a first glass substrate onto a translational stage and a second glass substrate onto the first glass substrate. In some examples, a gap is defined by contact made between the first and second glass substrates. In such examples, the gap can be up to about 10 μm. Additionally, in such examples, the method includes focusing a beam of light within the first glass substrate proximate to the gap. Further, in such examples, the method includes joining the first and second glass substrates to one another in a manner that closes the gap as a result of the focusing of the beam of light within the first glass substrate. In various examples, the first and second glass substrates each exhibit a transmittance of at least about 90% at a wavelength of the beam of light.

    Abstract: Disclosed are various embodiments of glass structures and the assembly of the same by way of laser welding. In one embodiment, the glass structures may comprise a lightweight mirror or other structure. In constructing a lightweight mirror, a core is assembled by creating laser welded joints between individual ones of a plurality of glass parts. At least one laser access opening is cut out in one or more of the glass parts or plates. In the assembling, various pairs of glass parts are positioned to create abutments therebetween. Further, a laser is directed through at least one laser access opening toward at least one of the abutments to create one or more of the laser welded joints.
