Abstract

The results of experimental and theoretical investigations of dynamic hologram recording and optical limiter improvement in nano-size porous glasses containing fullerene C₆₀ and toluene solution of C₆₀ are presented. 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 32 percent to 73 percent. Experiment showed that high diffraction orders appeared during dynamic hologram recording, and if the input intensity increased the number of orders increased, too. Presence of high diffraction orders caused more effective optical limiting because of laser energy redistribution. Taking into consideration different processes including reverse saturable absorption a model of dynamic hologram recording in fullerene solution waw carried out. The result of experiments were analyzed by numerical modeling. Analysis of computations and experimental results showed adequacy of the used model and perspective of applying of dynamic hologram recording in media containing C₆₀ toluene solution for improvement of optical limiting.
