Abstract
A method of photoaltering a material using a pulsed laser beam includes selecting a first pulse energy and a first focal point separation based on a relationship of pulse energy and focal point separation combinations enabling layer separation of the material by photoalteration, and scanning the pulsed laser beam along a scan region at the first pulse energy and the first focal point separation. The relationship has a slope and has a distinct change in the slope. The distinct change in the slope is associated with a second pulse energy of the relationships and the first pulse energy is equal to or less than the second pulse energy.
