Paper Abstract

In this work, we study self-focusing and self-defocusing effects, determination of photorefractive and thermal parameters in LiNbO3 and LiNbO3:Fe crystals using light-induced photorefractive and thermal lens with double-beam of mode-mismatched technique. Beyond to establish a best understand of photorefractive and thermal effects, their relations and limits in theses materials. And obtained good results in thermal lens effect (self-focusing) in LiNbO3 crystals and the photorefractive lens effect (self-focusing and self-defocusing).
