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 LiNb_O3 crystals and the photorefractive lens effect (self-focusing and self-defocusing).
