    Abstract: A method for processing a transparent workpiece that includes directing a laser beam output by a beam source onto a phase-adjustment device such that the laser beam downstream the phase-adjustment device is an Airy beam and directing the Airy beam onto a surface of the transparent workpiece. The Airy beam forms an Airy beam focal region in the transparent workpiece, the Airy beam of the Airy beam focal region having a maximum intensity of 100 TW/cm2 or less, the Airy beam of the Airy beam focal region induces absorption in the transparent workpiece, the induced absorption producing a curved defect in the transparent workpiece.

    Abstract: Prism coupling systems and methods for characterizing curved parts are disclosed. A coupling surface of a coupling prism is interfaced to the curved outer surface of the curved part to define a coupling interface. Measurement light is directed through the coupling prism and to the interface, wherein the measurement light has a width of 3 mm or less. TE and TM mode spectra reflected from the interface are digitally captured. These mode spectra are processed to determine at least one characteristic of the curved part, such as the stress profile, compressive stress, depth of layer, refractive index profile and birefringence.

    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.
