The surface relieves shaped in processes of thermoannealing of exposed polymer layers containing photosensitive admixtures are investigated. Several ways of resolving ability improvement of the relief recording are proposed and implemented experimentally. They are based on: (1) retardation of deformation reate, (2) depression of glass transition temperature of a polymeric matrix, (3) considerable increase of annealing temperature of the samples and (4) overlapping of the recording and thermal developing processes under photorelief shaping by one laser pulse. The last method has made it possible to record surface gratings with spatial frequencies in the limits of 50-1500 mm-1.
