Paper Abstract

We demonstrated experimentally the formation of the photorefractive filament array in PDMs by a femtosecond pulse laser. Using an optical microscopy and a fast CCD camera, we recorded the formation processes. The results showed that, by special design of the femtosecond laser parameters and the optical configurations, filaments can be placed in an orderly 1D or 2D arrangement array, and be reflected. Based on these observations, we have established a theoretical model to simulate the filaments.
