A method for laser processing a transparent workpiece includes forming a contour line having defects in the transparent workpiece, which includes directing a pulsed laser beam oriented along a beam pathway through a beam converting element and through a phase modifying optical element such that the portion of the pulsed laser beam directed into the transparent workpiece includes a phase shifted focal line having a cross-sectional phase contour that includes phase contour ridges induced by the phase modifying optical element and extending along phase ridge lines. Moreover, the phase shifted focal line generates an induced absorption within the transparent workpiece to produce a defect within the transparent workpiece including a central defect region and a radial arm that extends outward from the central defect region in a radial defect direction oriented within 20 of the phase ridge lines of the phase shifted focal line.

An object of the invention is to provide a multilayer glass which can be manufactured by a simple process. To solve the above problem, the multilayer glass according to the invention includes a first glass substrate, a second glass substrate that faces the first glass substrate at an interval of a predetermined space, and a sealing part that seals a periphery of an internal space defined by the first glass substrate and the second glass substrate. The sealing part is formed with a sealing material containing low melting point glass. The internal space is in a vacuum state. The first glass substrate includes an exhaust port that is provided to be included in a projection part of the sealing part when being projected in a lamination direction of the first glass substrate and the second glass substrate. The exhaust port is blocked by the sealing material (see FIG. 3).

The present disclosure provides a glass ceramic composite electrolyte comprising gadolinium doped ceria and glass composite with desired ionic conductivity in the temperature range of 400 to 600 C., suitable for applications in solid oxide fuel cells. Also disclosed is a process for the preparation of the glass ceramic composite electrolyte.

A photochromic glass that includes a base glass and a photochromic agent is described. The base glass is a modified boroaluminosilicate glass and the photochromic agent is a nanocrystalline cuprous halide phase. The photochromic glass exhibits a sharp cutoff in the UV or short wavelength visible portion of the spectrum along with an absorption band at longer wavelengths in the visible. The nanocrystalline cuprous halide phase includes Cu.sup.2+, which provides states within the bandgap of the cuprous halide that permit the glass to absorb visible light. Absorption of visible light drives a photochromic transition without compromising the sharp cutoff. The nanocrystalline cuprous halide phase may optionally include Ag.

Alkali aluminosilicate glasses that are resistant to damage due to sharp impact and capable of fast ion exchange are provided. The glasses comprise at least 4 mol % P.sub.2O.sub.5 and, when ion exchanged, have a Vickers indentation crack initiation load of at least about 7 kgf.

A fiber sensor includes an optical fiber configured for operation at a wavelength from about 800 nm to about 1600 nm. The optical fiber includes a cladding that is defined by a fiber outer diameter and a core that is surrounded by the cladding. The core of the optical fiber has a Rayleigh scattering coefficient, .sub.s, that is controlled by controlling a concentration of one or more dopants in the core. The Rayleigh scattering coefficient is tuned to be within a predetermined range of an optimum Rayleigh scattering coefficient for a given total length, L, of the optical fiber. The predetermined range is from about 70% of the optimum .sub.s to about 130% of the optimum .sub.s.
