Schematic representation of melanin linear absorption and nonlinear excited-state transient absorption.
(a,b) Representation of melanin linear absorption along with one underlying Gaussian chromophore with three different possible bandwidths. Inset in (a) shows an average of experimentally measured linear (i.e., stationary) absorption spectra of melanin in human tissue. (c,d) Corresponding pump-probe signals using different pump-probe wavelength combinations. (Experimental pump-probe measurement are shown in Figs 3 and 5).
