Abstract

Abstract

We studied the effects of bromine substitution on the nonlinear absorption properties of aza-dipyrromethene dyes. Nonlinear absorption is measured at wavelengths of 1200, 1500, and 1700nm. At 1200nm, excited-state absorption due to two-photon excitation appears, and it is more pronounced in the brominated polymethine cyanine.
