N2 - Two efficient optical methods are demonstrated to improve the formation of surface relief grating (SRG). The SRG formation is realized by a two-beam interference technique (λ=532nm) in an azobenzene side-chain copolymer. An incoherent UV beam (λ=355nm) or an incoherent VIS beam (λ=532nm), called assisting beam, was used to accelerate the photoisomerization process of the cis-form ↔ trans-form cycle, resulting in an efficient formation of SRG. The dependence of the diffraction efficiency and the relief depth of the SRGs on the polarizations of both assisting beams were investigated showing two different assisting mechanisms.
