Left panel: optical micrographs of the final surface morphology for four different fluences. Right panel: corresponding images recorded using the self-emission of the irradiated material. Frame size: .
Temporal evolution of the fracto-emission of the ablated material for three different fluences above the damage threshold . Inset: expanded view of the early time behavior; the small peak marked by an arrow corresponds to scattered pump light.
Temporally integrated emission signal as a function of pump fluence as measured using two different color filters (BG 3 and RG 645).
