Photoinduced surface relief gratings (SRGs) formed on Azo polymer films by using a two-beam interference technique were observed and analyzed. The heights of the SRGs at various polarization combinations of two writing beams were measured and compared with the force distributions from various theoretical models. As a result, we could suggest a combined model of the optical gradient force model and the pressure gradient force model by which the measured data could be explained well.
