Originální abstrakt

Two-photon absorption (2PA) is nonlinear optical phenomenon. The main difference between one-photon absorption (1PA) and 2PA is that 2PA involves simultaneous absorption of two photons of half of the energy (or twice the wavelength) of one molecule. Because of this difference 2PA has many advantages in comparison with traditional 1PA and we can use it in many applications, for instance three dimensional fluorescence microscopy, lithographic nanofabrication, three dimensional data storage, optical power limiting, photodynamic therapy, and for the localized release of bio-active species. These applications require new dyes with high two-photon absorption cross-section. Two-photon absorption cross-section describes efficiency of 2PA process in molecule with the given wavelength. If we want to produce this dye, we have to understand the relationship between the chemical structure and 2PA properties. The aim of this contribution is the study of 2PA properties derivatives diketo-pyrrolo-pyrrole, particularly two-photon absorption cross-section. We use Nd:YAG laser with TWHM 30 ps as the excitation source. Rhodamine B and Rhodamine 6G were used as standards for measuring of two-photon excited fluorescence.
