Laser Micromachining


The laser micromachining (LMM) equipment can be used for engraving and creating micro-features in metallic substrates. The parts to be removed are locally vaporized using Nd:YAG laser and that vapor can be sucked with a vacuum pump. The laser micromachining equipment (V3+, laservall, Italy) is established in the Western Lab from a DST grant for the micro-fabrication lab.

Basic Principle:

The basic principle is similar to that of laser spot welding. The only difference is that in this equipment the mirror 3 and lens 4 are moved in such a way that the spot 5 can be moved to the required position.

Unique Features:

Features ranging from 50 μm to 1mm can be created very easily. The shapes that are difficult to manufacture using conventional machining can be created easily using LMM equipment.
