Abstract: The influence of the nonlinear absorption on the photobleaching of polymer PMMA/DR1 film is studied in this paper. The experimental results show that the photobleaching induced by the two-photon absorption at 1064nm wavelength can make the film's refractive index change, but this change will become saturated with the photobleaching time.
