Abstract

We report measurements of response time for the intensity-dependent absorption in a single BaTiO3 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 BaTiO3 crystals.
