Figure 1 | Burst-mode femtosecond welding method, process, and results. (a) Galvanometer-based welding system, weld samples, and welding path. (b) High-speed imaging result of the ultrafast laser welding process, showing the transient laser absorption process. (c) Linear and nonlinear absorption regions during the femtosecond laser welding process. (d) Non-Burst mode ultrafast laser welding results and its transient absorption process (acquired at 100 ms). (e) 6-Burst mode ultrafast laser welding results and its transient absorption process (acquired at 100 ms). In (d) and (e), (i) is the upper surface of the welds, (ii) is the cross-sectional profiles of the welds, (iii) is the cross-sectional profiles of the modified structure within the sapphire, and (iv) is the plasma morphology.
