Abstract
In this work results obtained on the marking of thermoplastics (polyethylene terepthalate, polyethylene napthalate and polyimide) using an ytterbium Q-switch pulsed laser are presented. In these experiments the fiber laser beam was directed onto the substrate by a laser scanner. A test form has been created to study the influence of variable laser parameters such as power level, repetition frequency and mark speed in microstructuring.
