Abstract

We report the theoretical and experimental results of dynamic holograms recording in nano-size porous glasses containing fullerine C₆₀ and its use for optical limiting. To record a grating with spatial frequency 20 mm^-1 we used laser pulses with 18 ns duration and 532 nm wavelength. Initial transmittance of the samples varied from 30% to 70%. We found that high diffraction orders appeared out of the medium during the experiment and investigated dependence self-diffraction on initial transmittance of the samples and in case when the samples were filled by toluene. It was found that the most effective self-diffraction is in situation when we use toluene and initial transmittance of the sample is nearly 70%. For explanation of our experimental results we made a numerical model of dynamic hologram in fullerene-containing media taking into consideration amplitude and phase grating forming during the pulse length. Our model showed good agreement with experimental results.
