摘要：
An improved method and apparatus for drilling tapered holes in workpieces with laser pulses is presented which uses defocused laser pulses to machine the holes with specified taper and surface finish while maintaining specified exit diameters and improved system throughput. A system is described which can also drill holes with the desired taper and surface finish without requiring defocused laser pulses.
