Patent ID: 7671297

Claim:
A method of laser drilling a vibrating workpiece, comprising: providing a workpiece engaged by a first vibrating frame of a vibrating machine, wherein the workpiece is vibrating substantially in unison with the first vibrating frame; providing a laser apparatus mounted to a second frame, wherein the second frame is substantially isolated from the vibrating frame and does not vibrate; providing a spherical focusing lens that is mounted to the first vibrating frame, wherein the spherical focusing lens is vibrating substantially in unison with the first vibrating frame; aligning the laser apparatus and the spherical focusing lens such that a laser beam emitted by the laser apparatus is directed through the vibrating spherical focusing lens to a target location on the vibrating workpiece; and causing the laser apparatus to emit a beam through the spherical focusing lens, wherein the beam is stationary with respect to the vibrating spherical focusing lens, and wherein the beam strikes the vibrating workpiece at the target location.
