Show moreSystems and processes for improved laser machining, such as micro machining, of a workpiece. Systems and processes involve directing at a first surface of the workpiece a laser beam and wherein at least the laser-irradiated region of the first surface of the workpiece is immersed in a liquid, and delivering to the liquid-immersed and laser-irradiated workpiece surface region at least a first ultrasound output from a first ultrasound device. The ultrasound output and the laser beam desirably impact the workpiece first surface substantially simultaneously. Sponsorship: Illinois Institute of Technology United States Patent Show less
