Temporal behavior of the intensity-dependent absorption in photorefractive BaTiO(3).
We report measurements of response time for the intensity-dependent absorption in a single BaTiO(3) crystal under conditions in which no photorefractive effect can be observed. The speed of response is found to increase with increasing intensity but in a sublinear fashion similar to that observed for photorefractive decay. This experiment provides unambiguous evidence for the intensity-dependent absorption in BaTiO(3) crystals.
