Processing Of Synthetic And Natural Diamond Dies With Ao Q-Switched Nd : Yag Laser

An old type HOLOBEAM type Nd:YAG laser system was upgraded to reach technical requirements for diamond and diamond like materials drilling. A particular alignment protocol was tested to assure the best quality of the hole geometry. Various processing procedures were tested and important differences in bore quality are noticed for different materials and laser operating regimes. Dedicated user friendly software was made to drive the laser beam and holder actuators, for different hole drilling geometries.
