Abstract

Among liquid crystal spatial light modulators (LC-SLMs), LC- SLM with the photosensitive layer based on polyimide is of the highest resolution and of the highest sensitivity. In the present paper resolution, sensitivity, and speed of LC- SLM with polyimide doped with fullerene (FDPI) have been investigated in comparison with those of LC-SLM with dye doped polyimide (DDPI). For the study the holographic technique has been applied using the second harmonic of a pulsed Nd-laser under condition of Raman-Nath diffraction. LC-SLMs with fullerene-doped polyimide has been found to show the highest sensitivity, which has been 10 times higher than that for other LC-SLMs. The effect has been due to a creation of additional donor-acceptor complexes in polyimide doped with fullerene. Diffraction efficiency of LC-SLM with FDPI is less than the one of LC-SLM with DDPI. This fact is related to faster relaxation of holographic grating in FDPI.
