Figure 5: Plots of normalised transmission versus distance from focus for porphyrin and composite solutions at low energies for (a) DETPP, (b) tTETPP, (c) cTETPP, (d) HETPP, and (e) OETPP. (f) The higher final transmittance compared with the initial transmittance indicates the destruction of molecules present in the solution. Porphyrin and composite solutions were at concentrations of 0.01 mg/mL, with onfocus intensities of (a) 0.12, (b) 0.13, (c) 0.14, (d) 0.25, (e) 0.23, and (f) 1.63575 GW/cm2 for porphyrin solutions and (a) 0.25, (b) 0.16, (c) 0.24, (d) 0.23, and (e) 0.19 GW/cm2 for composite solutions.
