Degenerate and non-degenerate two-photon absorption of coumarin dyes
Ismael A. Elayan, Alex Brown
Abstract
where the increase is in the range of 22% to 49%, depending on the coumarin as well as the relative energies of the two photons. This work aids in future investigations into various fluorophores to understand their photophysical properties for ND-2PA.
