(a) Spectral range of static photomodification (in gray) with respect to the extinction spectrum of polydisperse dimers or trimers (schematic representation). Highlighted in gray is the wavelength range of laser radiation where static modification occurs at a given radiation intensity. The middle of this range is λ mod, the wavelength corresponding to the maximum spectral extinction is λ max; (b) dependence of the shift of photomodification mid-range λ mod – λ max = Δ λ (relative to λ max) on the degree of domain polydispersity.
