The article reports on the widely use of lasers in a vast number of micromachining applications. Pulsed lasers are used to machine parts with features having dimensions measured in microns with tolerances. However, in pulse duration effects, long pulses allow more heat to diffuse into the surrounding material and produce larger thermal effects. While, shorter pulses reduce thermal damage. On the other hand, picosecond lasers are good at drilling, cutting, and milling difficult materials.
