From: Ultrashort pulse laser ablation of dielectrics: Thresholds, mechanisms, role of breakdown
Comparing single- and multi-short laser ablation.
(a) The crater volume as a function of laser fluence for irradiation with one (triangles) and five (squares) pulses. (b) Craters produced by 5 laser pulses at the regimes below (left) and above (right) the breakdown threshold (pulse repetition rate is 10 Hz). (c) Schematic illustration of accumulation effects leading to cleaner crater morphology and rim disappearance with number of pulses at high laser fluences (see text).
