Figure 2 | Femtosecond laser energy transient deposition processes in different Burst modes.  (a) Comparative analysis of laser energy deposition over a 1 ms interaction duration. (b) Comparison of initial plasma morphologies at heterogeneous interfaces. Plasma evolution and size variation characteristics under (c) non-Burst, and (d) 6-Burst femtosecond laser irradiation. (e) Plasma morphology at 150/9 ms under the 6-Burst mode. The image reveals a continuously growing tear-shaped structure within the sapphire due to nonlinear absorption, and a surface plasma on the Invar alloy dominated by linear absorption.
