摘要:
A detailed study of the transmittance of dye-doped LC-film in dependence on the excitation laser radiation intensity in different LC-phases (nematic and chiral liquid crystals) is presented. It should be underlined that these compounds are based on the same molecular basis (cyanobiphenyls and their derivatives). Transmittance of the investigated systems appeared to be independent on the light intensity in a wide power region. The observed effect could be associated with the dye re-absorption to a higher electron level with the “left” absorption equaling the fundamental one.
