Two-beam coupling of coherent optical beams using a photoconductor–thermoplastic device is discussed. Calculations of the optical gain as a function of various recording parameters are presented. A method to control the relative phase between the interference pattern of the recording beams to the resulting surface deformation is described. Experimental results demonstrate that a gain factor of close to 5 can be achieved.
