    摘要: A method of cutting an article (172) from a chemically strengthened glass substrate (110) includes generating a pulsed laser beam (108) from a laser source (106). The pulsed laser beam (108) may have a pulse duration of less than about 1000 fs and an output wavelength such that the chemically strengthened glass substrate (110) is substantially transparent to the pulsed laser beam (108). The pulsed laser beam (108) may be focused to form a beam waist (109) that is positioned in the same horizontal plane as an inner tensile region (124) of the chemically strengthened glass substrate (110). The beam waist (109) may be translated in a first pass along a cut line (116), wherein the beam waist (109) traverses an edge (111) of the chemically strengthened glass substrate. The beam waist (113) may then be translated in a second pass along the cut line (116) such that a crack (119) propagates from the edge (113) along the cut line (116) ahead of the translated beam waist (109) during the second pass.
