The Principles of Ablation

Considering the many types of materials involved in laser micro machining, selecting the most optimum laser can be a challenge. An understanding of material properties and laser characteristics are necessary for making the right selection. Laser micro machining is an ablation process. This means the material to be removed is…

Introduction to Laser Micro Machining

Overview: Laser micro machining includes laser ablation, surface structuring of tough materials, and routing to create wave-guides. Materials suited for laser ablation include: ceramics, glasses, metals, polymers, and semiconductors. Typical laser micro machining is done with pulses with a duration of nanoseconds to picoseconds. Ultra-fast lasers have pulses shorter than…
