Abstract

As the new method of machining, laser ablation has a lot of attractive advantages. The possibilities of dead end engraving and stable long term machining would be the great merits of micro-patterning to large metal mold which is used to the optical sheets for flat panel display for example. We developed pico-second laser machining system and manufactured micro-patterns on metal mold surface. And from those sample-machining results, we concluded it is possible to adapt this system to metal mold micro-pattern machining and decided to continue our development of laser machining.
