Abstract:
We report on a simple technique for the measurement of the recording response time in photorefractive materials. Three different material samples were successfully measured, and their response times, as well as their dependence upon the recording/measurement light irradiance, were also determined and compared with available data in the literature in order to assess the reliability of this technique.
