Three distinct incidence configurations were utilized, as illustrated in @figure-incidence: (i) normal incidence, where the laser incident perpendicularly to the epitaxial surface; (ii) grazing incidence, where the laser incident nearly parallelly to the epitaxial surface; and (iii) edge incidence, where the laser is incident at the wafer edge and perpendicularly to the edge surface.
