The crosslinking of a diacrylate mesogen was initiated in a holographic field created by 488nm wavelength laser beam. The holographic irradiation provided both energy for crosslinking of acrylate groups and the driving force to align mesogenic groups in the diacrylate mesogen. A template with localized molecular ordering in the diacrylate mesogen layer in a mesophase can be created by the holographic field, and is frozen up by in situ polymerization of the mesogen. The resultant polymer networks possess localized orientational order which was patterned by the holographic field.
