Cut Surface Characteristics. Fig. 3 and 4 are the top-view micrographs of silicon after laser ablation. More cut debris deposition can be obtained when a higher laser power was used. This is due to the increased amount of molten material that can be more expelled by the recoil pressure from the cut channel under the high laser power. A larger molten droplet was found to land and solidify closer to the cut edge while smaller debris was deposited further away from the cut. As presented in the micrographs, the width of deposition region was approximately 100 µm from the kerf edge.
