Abstract: Cross section of the two-photon absorption in 7-dialkylamino-3-(3-pyrazolinyl)coumarins in acetone and polymethylmethacrylate films has been found to be dependent on the substrate and medium nature. 7-Dialkylamino-3-[1,5-diaryl(3-pyrazolinyl)]coumarins are shown to be effective in the photosensitive media with excitation at 1060 nm for optical recording of information.
