Picosecond high-repetition-rate pulsed laser ablation of dielectrics: the effect of energy accumulation between pulses [PDF]
, 2015 We report experiments on the ablation of arsenic trisulphide and silicon using high-repetition-rate (megahertz) trains of picosecond pulses. In the case of arsenic trisulphide, the average single pulse fluence at ablation threshold is found to be >100 ...
