Abstract
Three types of hard materials Borosilicate glass, Soda lime glass and Quartz have been ablated using stainless steel, copper, brass and silver as target materials. Various combinations of substrates and target materials have been investigated to study effects of current on an ablated depth of the substrate and to find optimum values of current and ablated depth without formation of crack on the substrate; the damage to the glass surface was due to a high absorption after the first few pulses. Optimization of LIPAA ( Laser Induced Plasma Assisted Ablation) process parameters have been investigated using a 50 watt acoustic-optic Q-switched Nd:YAG solid laser .
