Abstrakt: In this work, thermal lens spectroscopy was used to analyze the thermo-optical properties of the transparent ceramic lead lanthanum zirconated titanate or PLZT 10/65/35 as a function of the external electric field, from 0 to 1200 kV/m. The results show that when increasing the electrical field in the sample, the temperature coefficient of optical path length presented parallel and perpendicular components. For the parallel component, the electrical field makes this parameter alternate from positive to negative and from negative to positive and so on. This behavior as a function of an external electric field may be useful in the development of electro-optical devices with this transparent ceramic. [ABSTRACT FROM AUTHOR]
