The direct formation of surface relief gratings (SRG) in amorphous chalcogenide and low molecular weight azo-benzene containing organic glass films during holographic recording was studied. It has been shown that the course of SRG growth curves can be divided in three development stages: an induction period of photo-induced birefringence, linear growing of SRGs and saturation of SRG inscription process. The influence of the photo-induced birefringence on the relief formation process in amorphous As-S and As-S-Se films was evaluated and compared with the measurements on azo-benzene containing organic glass films. It was shown that the saturation of SRG formation depends on the surface tension of recording material..
