Introduction to micromachining with femtosecond laser pulses Available to Purchase

Micromachining with lasers is an evolving technology. Initially laser micromachining was based on continuous-wave or long-pulse lasers. However, these lasers, transferred heat to the work piece, introducing limitations in the precision and quality of the machining process. Machinists can minimize the negative effects of heat transfer using pre- and post-processing techniques, but these increase the complexity and cost of the operation.

Scientists at the University of Michigan have since discovered that machining with laser pulses of very short duration minimizes heat flow to surrounding material. This discovery opened the way for fine laser micromachining.
