Abstract: The present invention is a method for separating a workpiece from a common substrate. It includes the steps of providing the workpiece, generating, within a beam source, a beam of laser pulses configured to modify a portion of the workpiece, determining a depth for creating a modified region based upon a characteristic of the workpiece and modifying a plurality of regions within the workpiece to form a plurality of modified regions. Modifying the plurality of regions includes directing the beam of laser pulses from an output of the beam source onto the workpiece, causing relative motion between the workpiece and the output of the beam source while directing the beam of laser pulses onto workpiece, and modifying a characteristic of the pulses of the beam upon generating a number of pulses which generally correspond to creating the modified regions to the determined depth.

Abstract: A beam positioner can be broadly characterized as including a first acousto-optic (AO) deflector (AOD) operative to diffract an incident beam of linearly polarized laser light, wherein the first AOD has a first diffraction axis and wherein the first AOD is oriented such that the first diffraction axis has a predetermined spatial relationship with the plane of polarization of the linearly polarized laser light. The beam positioner can include at least one phase-shifting reflector arranged within a beam path along which light is propagatable from the first AOD. The at least one phase-shifting reflector can be configured and oriented to rotate the plane of polarization of light diffracted by the first AOD.

Abstract: The present invention relates to laser marking articles. In particular it relates to laser marking articles by laser ablating a coating applied to the article which reveals the surface of the article underneath, thereby forming the mark by the contrasting appearance between the revealed surface of the article and the adjacent remaining coating. Laser parameters are selected to provide uniform, commercially desirable appearance and avoid damage to the underlying surface while maintaining acceptable system throughput. In particular the laser pulse envelope is tailored to provide desirable appearance while maintaining acceptable system throughput.
