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: 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: An optical fiber for converting a Gaussian laser beam into a Bessel laser beam may include a first segment optically coupled to a second segment with a transition region, the first segment having a first outer diameter greater than a second outer diameter of the second segment. The first segment may include a first core portion with a first cladding portion extending around the first core portion. The first core portion may have an annular core region with a relative refractive index relative to the first cladding portion. The second segment may include a second core portion with a second cladding portion extending around the second core portion. The second core portion has a relative refractive index relative to the second cladding portion and the relative refractive index of the first annular core region may be substantially equal to the relative refractive index of the second core portion.

Abstract: A glass container including a body having a delamination factor less than or equal to 10 and at least one marking is described. The body has an inner surface, an outer surface, and a wall thickness extending between the outer surface and the inner surface. The marking is located within the wall thickness. In particular, the marking is a portion of the body having a refractive index that differs from a refractive index of an unmarked portion of the body. Methods of forming the marking within the body are also described.

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.
