A Prototype Femtosecond Laser System for Precise Micromachining

Abstract

In this article we present a concept of a prototype design of the femtosecond laser micromachining system and a femtosecond solid-state Yb:KYW laser developed in our laboratory. Ultra-short laser pulses have many advantages over the long pulses laser micromachining, due to their unique ability to interact with different materials without transferring heat to them. This allows very precise and pure laser-processing, clean cuts and sharp edges. A femtosecond laser micromachining device presented here is equipped with a synchronized motion control system. Application of this advanced motion system results in the maximum use of the femtosecond laser potential for high-precision micromachining.
