Determination of plasma ignition threshold fluence during femtosecond single-shot laser ablation on metallic samples detected by optical emission spectroscopy
The minimum laser fluence needed for plasma ignition on a sample during single-shot femtosecond laser ablation has been determined for a set of metals and alloys. Threshold fluence values ranged between 4 and 9 J cm −2 for ablation craters with a diameter of 40 μm. The craters exhibited similar size...
