Dynamic holograms recording in fullerene-containing solid-state media by 300 ps and 20 ns laser pulses

摘要

The results of experimental investigation of dynamic holograms recording by 20 ns and 300 ps laser pulses in fullerene-containing solid-state matrices are presented in this paper. The spectral analysis in range 300-700 nm shows correlation between efficiency of dynamic holograms recording and presence of absorption band at nearly 330 nm. We use two types of solid-state matrices: porous glass and polymethylmethacrylate hosts, which were filled with fullerene C_(60). From the dynamic holograms recording experiments and from the spectral analysis we obtained data on sensitivity and stability of the media, which can be used later in practical applications like all-optical switching.
