Laser micro-machining of Borofloat 33 glass. Influence of peak laser fluence on: (a) mean depth, (b) surface roughness, and (c) material removal rate (MRR) for different values of hatch distance (ΔH = 2, 4, and 6 μm). Also it was found that the mean depth increases linearly with increasing energy dose, as shown in (d). All data are valid for λ = 515 nm, 2ω0 = 24 μm, PRF = 20 kHz, v = 40 mm/s. Datasets used to plot these graphs are in the Supplementary Materials (see Table S1).
