摘要： In the method for cutting flat glass work pieces a laser beam having a linear beam profile followed by a cold spot is moved along a curved dividing line (2) on the work piece. A linear focal point (1) is produced on the work piece by scanning the laser beam. Trajectory data from the curved dividing line (2) is made available during every scanning motion and scanning is controlled so that all points of the curvilinear focal point (1) lie on or coincide with the curved dividing line (2). A length of the curvilinear focal point is adjusted according to the curvature of the curved dividing line by adjusting scanning amplitude of the scanning motion. Preferably the laser beam output is adjusted as a function of the length of the curvilinear focal point.

摘要： A method and apparatus for laser cutting a target material is disclosed. The method includes the steps of generating laser pulses from a laser system and applying the laser pulses to the target material so that the laser pulses cut through the material. The laser pulses have an approximately ellipse shaped spot, have a temporal pulse width shorter than about 100 nanoseconds, and have an energy density from about 2 to about 20 times the ablation threshold energy of the target material. The laser pulses are applied to the material such that the major axis of the ellipse shaped spot moves parallel to the cutting direction. The spot has a leading edge and a trailing edge on the major axis, and the energy density of each laser pulse increases from zero to a maximum along the leading edge and decreases back to zero along the trailing edge. The apparatus is a laser system for cutting a target material that includes: a seed laser system for producing a first pulse laser beam; a laser amplifier for amplifying the first pulse laser beam to produce an amplified pulse laser beam; a harmonic generation system for converting the amplified pulse laser beam into a second pulse laser beam having a shorter wavelength; a focussing system for focussing the second pulse laser beam to an approximately ellipse shaped third pulse laser beam; and a motion control system for moving a target material contacted by the third pulse laser beam.

摘要： A controller outputs a first event signal having a periodical waveform and a second event signal having a periodical waveform synchronizing with the first event signal. A first laser source radiates a first pulse laser beam having a wavelength in an ultraviolet range, synchronously with the first event signal. A second laser source radiates a second pulse laser beam having a wavelength in the ultraviolet range, synchronously with the second event signal. A converging optical system converges the first and second pulse laser beams at the same point. A holder holds a workpiece at a position where a pulse laser beam converged by the converging optical system is applied.

摘要： A slider fabrication assembly and method for making the same are provided. A slider is formed on a substrate. A corrodible component of the slider is exposed to an environment in contact with the slider. A kerf region of the substrate is positioned adjacent to the slider. The kerf region is removable from the slider. A sacrificial anode is embedded in the kerf region and exposed to the environment. The sacrificial anode is electrically coupled to the corrodible component of the slider thereby forming an electrochemical cell. The sacrificial anode is less noble, i.e., more corrodible, than the corrodible slider component, and thus corrodes first. When the kerf region is removed, the corroded sacrificial anode is removed as well.
