| Abstract: | The laser marking experiments to polyvinyl chloride samples are made with 308nm excimer laser,it is found that a fine and visible pattern can be acquired in the sample surface which is irradiated by a proper fluence laser pulse.Besides,this marking method is efficient,high speed,and very clear,the heat effect on all around is very miniature.The condition of marking is optimized in the experiments.In this paper the marking procedures are analyzed and the marking mechanism is studied preliminarily. |
