Abstract:
Methods of and devices for forming edge chamfers and through holes and slots on a material that is machined using a laser, such as an ultrafast laser. The shaped material has predetermined and highly controllable geometric shape and/or surface morphology. Further, a method of and a device for preventing re-deposition of the particles on a material that is machined using a laser, such as an ultrafast laser. A fluid is used to wash off the particles generated during the laser machining process. The fluid can be in a non-neutral condition, with one or more chemical salts added, or a condition allowing the coagulation of the particles in the fluid, such that the particles can be precipitated to avoid the reattachment to the machined substrate.

Claim (Index 1):
An apparatus for laser processing a stock of brittle material, the stock of brittle material having a front surface and an opposite back surface, the apparatus comprising:\n a material holder for supporting the stock of brittle material; a fluid reservoir holding a liquid solution and positioned such that the back surface of the stock of brittle material is contact with the liquid solution, the liquid solution having a zeta potential of less than about 10 mV; and a laser generating pulsed laser beam, said pulses being in the picosecond or femtosecond range, and with the focus of the laser beam being adjustable such that during processing, the laser beam is incident on the front surface of the stock of brittle material and wherein the focus of the laser beam is initially at the back surface of the stock of brittle material and then the focus is moved towards the front surface of the stock of brittle material in order to removed material from the stock of brittle material by ablation, the material removed by ablation being in the form of debris particles, the liquid solution coagulating the debris particles in the liquid solution, the liquid solution thereby preventing the material removed by ablation from reattaching to the stock of brittle material.
