Abstract
Laser marking systems (60, 80, 160, 250) having increased part throughput are obtained by disposing diffractive optics (70, 70A, 94, 170, 252) across a primary laser beam. Preferred diffractive optics for high power marking lasers are defined in optical materials with discrete surface levels.
