Abstract
Femtosecond (fs) lasers are widely employed in precision micro-machining due to their ultrashort pulse durations and high peak powers, enabling material removal with high resolution and minimal heat-affected zones. This study investigates the ablation behavior of stainless steel and aluminum using two fs laser regimes: a GHz burst laser and a single-pulse fs laser. The GHz burst laser operated at a 2 GHz intra-burst repetition rate and 200 kHz burst rate under various burst durations, while the single-pulse laser operated at 400 kHz. Line scribing and single-shot ablation tests were performed to analyze how burst structure, repetition rate, and energy delivery affect ablation behavior.
