    Abstract

    The effect of environmental humidity on the photosensitivity and real-time diffraction efficiency has been studied in dichromated polyvinyl alcohol (DC-PVA) films with and without external electron donors. High relative humidity has been found to significantly improve the photospeed and the real-time diffraction efficiency for almost all of the studied formulations. The results and possible photochemical reactions in the recording mechanism are briefly discussed.
