Dye-doped liquid crystalls (LCs) exhibit significantly enhanced photoinduced reorientation compared to undoped LCs. In this study, photoresponsive behavior of LC systems doped with photostable fluorescent dyes were investigated. Photoresponsive behavior of the LC system was evaluated by the self-diffraction pattern formed upon irradiation of a linearly polarized Ar^+ laser beam. When the laser beam was incident on the sample cells, clear diffraction pattern was observed for the sample cells doped with Coumarin 6 and Coumarin 7. Thus, they were found to act as a trigger for the photoinduced reorientation.
