| Abstract: | Ablating diamond grain by acoustic-optic Q-switched YAG pulsed laser,a investiga tion had been done into affected layer and micro-crack of the grain influenced by laser parameters. First,the diathermanous and mathematic model were estabished to process simulation calculation through ablation experiment and actual check to validate,then to analyze their reasons.The pulsed frequency is the primary factor to influence affected layer and surface micro-crack,others beneficial rules are concluded synchronously. |
