Background: The most popular photorefractive material is BaTiO3 due to its large electrooptic coefficients (EO) as well as its dielectric properties at room temperature.
Objective: The doping of this crystal with rhodium (BaTiO3: Rh) has as a main goal to investigate possibility of working near infrared domaine (I.R).
Method: In this paper, we propose an experiment of the evolution of the electro-optical coefficient (EO) r33 and dielectric constant ε33 as function of temperature from 20°C to 50°C for a new crystal BaTiO3: Rh.
Result: We show that electro-optic and dielectric properties are the same behavior versus temperature variation.
