“Domain” -Like Reorientation in Dye Doped Nematics Induced by High-Power Radiation

Abstract
High power laser (P∼106W/cm2) induced “domain”-like reorientation in homogeneously oriented by silicon monoxide dye doped liquid crystals (DDLC) has been observed. Reorientation can be accompanied with writing of static gratings that are induced by a radiation on monoxide layer surface.
