Abstract:

The two-photon excited fluorescence of two merocyanine dyes excited by nanosecond radiation of an Nd:YAG laser (532 nm) is investigated. The two-photon absorption cross sections of merocyanines are measured and equal to 25 ± 5 and 115 ± 15 GM. Features of nonlinear absorption of the investigated molecules are discussed.

Keywords:

two-photon absorption, merocyanine dyes
