Abstract

We demonstrate numerically the use of biburst pulses in femtosecond laser ablation of metals. Using a two-temperature model, we calculate the crater size formed from ablation of copper as the number of bursts and intraburst, and separation times were varied. Here we show that due to heat accumulation effects, the crater formed is larger when both burst and biburst pulses have longer separation time. The shape of the crater thru calculation of relative aspect ratio show narrower craters for longer separation time with more bursts. Our results can guide researchers in precise processing of desired structures on surfaces of metals using biburst pulses.
