Owing to their very short pulse durations - sometimes less than the target material's conduction time - and very high peak powers, ultrafast (femtosecond and picosecond) laser systems offer unique material processing possibilities such as “cold machining” of parts with no/negligible heat affected zone. In fact, this short pulse width/high peak power, combination enables processing capability of almost any material, including metal, plastics, ceramics or glass.

Ultra-fast laser micromachining has been getting a lot of press lately; does it live up to its billing? In my view, ultra-fast micromachining has terrific potential, but I’d like to temper the enthusiasm with a little dose of reality. Amada Miyachi America has a new micromachining applications laboratory set up with a variety of different ultra-fast laser micromachining sources and motion platforms, so I am in a perfect position to show some examples of what ultra-fast laser micromachining can do from a laser independent systems integrator perspective
