Laser Micro Machining Application Examples

Selection of the optimum laser wave length, laser pulse parameters, beam delivery optics, assist gases has a critical effect on the quality for each application for each type of material. A sequence of controlled laser pulses (pulse duration and frequency) – maximizing peak power density and optimizing pulse parameters) delivers a precise amount of energy to the material.

Laser processing; drilling, cutting and scribing of various materials; metals, plastics, ceramics, silicon, composites are widely used laser processes for numerous industries and applications, e.g., electronic – semiconductor, medical, sheet metal, solar cell, micro cooling, machining and fabrication.
