The ferroelectric materials with high photovoltaic properties are of interest for the new optical devices such as photostrictive ceramic actuators. In pursuit of these high performance photostrictive materials, the present research examines the influence of sample thickness and surface roughness on photostriction of WO3 doped PLZT ceramics. A model for the calculation of optimum sample thickness having maximum photostrictive response is proposed. This model agrees well with the experimental results, and it will help in designing the photostrictive devices.
