摘要： An improved method for laser machining features in brittle materials such as glass 8 is presented, wherein a tool path 10 related to a feature is analyzed to determine how many passes are required to laser machine the feature using non-adjacent laser pulses 12. Laser pulses 12 applied during subsequent passes are located so as to overlap previous laser spot locations by a predetermined overlap amount. In this way no single spot receives excessive laser radiation caused by immediately subsequent laser pulses 12 being applied adjacent to a previous pulse location.

摘要： A laser machining process is described for laser 72 machining glass or glass-like materials 62. This process machines articles 60 with chamfered edges 96 in one manufacturing operation. Chamfered edges 96 are desirable in glass and glass-like materials 62 because they resist fracturing or chipping and eliminate sharp edges. Producing chamfered 96 articles 60 in one manufacturing operation is desirable because it can save time and expense by eliminating the need to transfer the article to a separate machine for chamfering 96 after laser 72 machining. Alternatively, it can permit use of less expensive equipment because the same laser 72 used for machining can be used to form the chamfer 96 instead of having a separate process perform the chamfering 96.
摘要翻译：描述激光加工过程用于激光72加工玻璃或玻璃状材料62.该过程在一次制造操作中加工具有倒角边缘96的制品60。倒角边缘96在玻璃和玻璃状材料62中是理想的，因为它们抵抗断裂或碎裂并消除锋利的边缘。在一次制造操作中生产倒角的96个制品60是合乎需要的，因为通过在激光72机械加工之后不需要将制品转移到单独的机器进行倒角96，它可以节省时间和费用。或者，它可以允许使用较便宜的设备，因为用于机械加工的相同激光器72可以用于形成倒角96，而不是使用单独的工艺来执行倒角96.

摘要： Systems and methods reduce or prevent back-reflections in a laser processing system. A system includes a laser source to generate an incident laser beam, a laser beam output to direct the incident laser beam toward a work surface along a beam path, and a spatial filter. The system further includes a beam expander to expand a diameter of the incident laser beam received through the spatial filter, and a scan lens to focus the expanded incident laser beam at a target location on a work surface. A reflected laser beam from the work surface returns through the scan lens to the beam expander, which reduces a diameter of the reflected beam and increases a divergence angle of the reflected laser beam. The spatial filter blocks a portion of the diverging reflected laser beam from passing through the aperture and returning to the laser beam output.

摘要： Laser direct ablation (LDA) produces patterns cut into a dielectric layer for the formation of electrically conductive traces with controlled signal propagation characteristics. LDA processing includes selecting a dose fluence for removing a desired depth of material along a scribe line on a surface of a workpiece, selecting a temporal pulsewidth for each laser pulse in a series of laser pulses, and selecting a pulse repetition frequency for the series of laser pulse. The pulse repetition frequency is based at least in part on the selected temporal pulsewidth to maintain the selected dose fluence along the scribe line. The selected pulse repetition frequency provides a predetermined minimum overlap of laser spots along the scribe line. The LDA process further includes generating a laser beam including the series of laser pulses according to the selected dose fluence, temporal pulsewidth, and pulse repetition frequency.

摘要： An improved method for laser machining features in brittle materials such as glass 8 is presented, wherein a tool path 10 related to a feature is analyzed to determine how many passes are required to laser machine the feature using non-adjacent laser pulses 12. Laser pulses 12 applied during subsequent passes are located so as to overlap previous laser spot locations by a predetermined overlap amount. In this way no single spot receives excessive laser radiation caused by immediately subsequent laser pulses 12 being applied adjacent to a previous pulse location.
