A method of directing a pulse of laser energy though a workpiece. The workpiece has: a substrate that transmits the laser energy; focusing elements on a surface of the substrate proximal to the laser that focus the laser energy; and a coating on the substrate distal to the laser that absorbs a portion of the laser energy. Each focusing element focuses the laser energy to a point that removes or ablates a portion of the coating from the substrate to produce a hole in the coating.
