Comparison of laser-induced responses in ex vivo pigmented porcine skin after irradiation with MLA and DOE at various radiant exposures (H0 in J/cm2) and focal depths (FD in mm): (a) top-view images of laser-irradiated skin surface, (b) spatial distributions of micro-beam sizes acquired from middle line (red dashed line) of macro-beam spots (H0 = 3.0 J/cm2), and (c) overall micro-beam sizes measured from macro-beam spot (H0 = 3.0 J/cm2). Note that cyan dashed lines in (a) indicate the boundary of the macro-beam spots on the skin surface (bar = 2 mm; ***p < 0.001 vs. MLA). Gray areas in (b) represent the deviations for the measured micro-beam sizes.
