Fullerene-doped π-conjugated organic systems under infrared laser irradiation

An optical limiting (OL) effect of the laser radiation over IR range in organic compounds based on polyimide has been studied. The non-linear transmission at a wavelength of 1315 nm as well as spectral properties of the compounds have been investigated. The results obtained have been explained by th...

Description
Summary:An optical limiting (OL) effect of the laser radiation over IR range in organic compounds based on polyimide has been studied. The non-linear transmission at a wavelength of 1315 nm as well as spectral properties of the compounds have been investigated. The results obtained have been explained by the donor–acceptor interaction mechanism that affects non-linear-optical properties of organic molecules. The fullerene-doped polyimide structures have been determined to be effective OL materials for attenuating a power density of more than 1 J cm −2 in the IR range.
