fig 1 (IMAGE) Compuscript Ltd Caption (a) Pump-probe microscopy setup for the ablation in water. For the analysis of the ablation process in air, no cuvette is used, otherwise the setup is the same. (b) Image post processing of the three recorded images. The images of the pristine surface (R0), during the ablation process (R(Δt)) and after the ablation process has finished (Rinf) were used to calculate the transient (ΔR/R0) and final state (ΔRinf/R0) relative reflectivity change. The red dashed circles mark the transient laser-modified area ΔA and the final laser-modified area ΔAinf. Credit OEA Usage Restrictions Credit must be given to the creator.
