Photorefractive effect in Pb-based relaxor ferroelectric materials

In this work, we present a review of recent works on photorefractive effect in Pb-based relaxor ferroelectric material. The review is based on the well known Kukhtarev's model [1] and recent experimental photorefractive two beam coupling works by He et al [2] and Abe et. al. [3,4]. We also suggest the generation of higher orders and other applications such as optical correlation, phase conjugation, which may be worked well with a Pb-Based relaxor ferroelectric materials. From this work, we have seen the bright future of the research in photorefractive effect using the Pb-based relaxor ferroelectric materials.
