Abstract
A laser drilling process forms a plurality of holes in a pharmaceutical dosage form (12). A high power carbon dioxide laser is steered by an acousto-optic beam deflector (16) with various mirrors (17, 18, 19) and lenses (22, 23, 33, 34, 35) to the dosage form to produce holes at rates up to 100,000 units per hour.
