Abstract

Three-dimensional optical memories which utilize two-photon processes have been proposed for use as a radiation dosimeter. The 'bits' stored by the optical memory are altered by the passage of radiation and can yield information about the dose and energy. In this work, the 'write' process of a two-photon optical memory is examined. This process uses a crossed-beam excitation scheme. By considering the spatial and temporal properties of the excitation sources used to drive the two- photon transitions, conditions are derived under which the number of absorption events due to the crossed-beams acting together outnumber the background events.
