In this work, we have investigated the two-photon absorption (2PA) degenerate cross-section spectrum for perylene derivatives using the Z-scan technique with femtosecond laser pulses. All perylene derivatives studied present large 2PA cross-sections, only comparable to the best ones reported in the literature. The results achieved in the present investigation indicate perylene derivatives as promising materials for two-photon applications. ©2005 Optical Society of America.1277-1279engDerivativesLaser pulsesLight absorptionPhotonsQuantum opticsFemtosecond laser pulsesNonlinear absorptionPerylene derivativesTwo-photon absorption (2PA)Nonlinear opticsTrabalho apresentado em evento10.1109/QELS.2005.1549104Acesso aberto2-s2.0-27144529639
