Abstract: 
We have demonstrated that holograms may be recorded in polyvinyl alcohol/acrylamide photopolymer dry films using pulsed laser exposure with a pulse length of 8 ns. We also studied the effect of the pulse fluency together with the number of pulses necessary to obtain maximum diffraction efficiency. The recording was performed using a holographic copying process. The original was a grating of 1000 lines/mm processed using silver halide sensitized gelatin. Diffraction efficiencies of 55% were obtained with sensitivities similar to those reached with the same material and cw exposure, without the need for pre-processing or final processing of the gratings.
