What are the applications of picosecond laser cutting machines?

Picosecond laser cutting machineIt is mainly composed of picosecond laser, light guide, focusing system, displacement platform, computer control system and other auxiliary systems. Picosecond laser is an ultra-short pulse laser with high peak value. The principle is that after the laser beam is focused, it is irradiated on the workpiece, and the material is instantly heated with high energy to melt or evaporate it.

It has many advantages, mainly the following:

1. Real cold processing, basically no carbonization;

2. Ultra-short pulse, energy released at the picosecond level, small heat-affected zone, negligible, no micro-cracks;

3. Fast speed, picosecond repetition frequency is very high, and the galvanometer speed is fast;

4. Fine cutting effect, picosecond processing uses small single pulse energy, high-frequency processing, and the processing surface is finer;

5. There are many processing materials, suitable for processing various materials.

Cutting, punching, surface microstructure (bionic structure), scribing, grooving of ultra-thin metal materials (copper, gold, silver, aluminum, titanium, nickel, stainless steel, molybdenum, etc.), flexible materials (PET, PI, PP, PVC, Teflon, electromagnetic film, adhesive film, etc.), graphene, carbon fiber, silicon wafer, ceramics, FPC and other materials, as well as micro-machining of polymer materials and composite materials.
