    Abstract: Systems for and methods of characterizing the thickness profile of laminated glass structures are disclosed, wherein the laminated glass structure has at least one gradual transition region between adjacent glass layers. The method includes sequentially focusing laser light at different focuses along a line within the laminated glass structure. The sequentially formed focuses define corresponding micro-volumes from which fluorescent light emanates due to a multiphoton process. The variation in the intensity of the detected fluorescent light from each micro-volume as a function of distance into the laminated glass structure is used to determine the relative locations of the multiple layers and the at least one gradual transition region.

    Abstract: Systems and methods of for measuring birefringence and stress in a sample made of ion-exchanged glass or a ceramic are disclosed, wherein the method includes digitally capturing TE and TM angular spectra of intensity versus pixel number for the sample. The TE and TM angular spectra are processed to minimize differences between respective regions of the TE and TM angular spectra. The amount of shift in pixels that best overlaps the processed TE and TM spectra is determined. The birefringence B is calculated by multiplying the pixel shift by the index resolution. The stress is calculated by multiplying the birefringence by the stress-optic coefficient.

    Abstract: Cutting a desired final shape in a glass sheet, wherein the glass sheet is about 0.3 mm or less in thickness by applying a laser beam to the glass and continuously moving the laser relative to the glass along the cutting line. The laser is of a circular shape, and cooling fluid is applied simultaneously with the application of the laser, such that the cooling fluid at least reduces the temperature of the glass in order to propagate a fracture in the glass. The method includes controlling at least one of: (i) an energy density of the laser, (ii) a velocity of the laser relative to the glass along the cutting line, (iii) a fluid flow of the cooling fluid, and (iv) a minimum radius of curvature of the cutting line, such that a B10 edge strength of a cut edge of the glass is at least about 300 MPa.
