<gwmw class="ginger-module-highlighter-mistake-type-3" id="gwmw-15614355837262930584730">Nonlinear optical effect</gwmw>, which is capable to change <gwmw class="ginger-module-highlighter-mistake-type-3" id="gwmw-15614355837262604295845">optical properties</gwmw> depending on light intensity, has attracted much attention. In particular, liquid crystals doped with dye molecules can control transmittance in response with molecular reorientation based on nonlinear optical effect. So far, a focused laser beam has been used to induce such nonlinear optical response of liquid crystals, which strictly constraints the applicable situation of the systems. In this study, we investigated <gwmw class="ginger-module-highlighter-mistake-type-3" id="gwmw-15614355820767258737407">photoresponsive behavior</gwmw> of polymer-stabilized dye-doped liquid crystals by collimated beam irradiation.
