The laser intensity modulation method (LIMM) was applied to the investigation of polarization distributions in sandwich cells of a side chain liquid crystalline polymer (LCP). The thermal poling procedure using a pulsating electric field was carried out for the nematic phase at 80°C. After cooling down the samples to room temperatureTR(i.e. below the glass transition temperature,Tg) a rather perfect alignment of the side chains could be obtained. Our first LIMM investigations atTRshow a nearly homogeneous polarization profile in the LCP layer.
