This project aims to study the fundamental processes governing interaction of ultrafast light pulses with an important class of ferroelectric materials. In particular, it will investigate the physics of light-induced ferroelectric domain reversal in various types of ferroelectrics. Project outcomes will lead to the development of a novel, ultrafast laser domain patterning technique for application in nonlinear photonics, optical memories, and photovoltaics. This technique will be employed to create the first example of three-dimensional domain patterns for versatile wave interactions. This project expects to expand Australia's knowledge in ultrafast laser engineering of materials and contribute towards its rapid uptake by industries, with great potential for commercialisation.

本项目旨在研究超快光脉冲与一类重要的铁电材料相互作用的基本过程。特别是，它将研究各种类型的铁电体中光致铁电畴反转的物理学。项目成果将导致一种新的，超快激光域图案化技术的发展，应用于非线性光子学，光学存储器和photopolics。这种技术将被用来创建第一个例子的三维域模式的多功能波的相互作用。该项目预计将扩大澳大利亚在超快激光材料工程方面的知识，并有助于其迅速被行业吸收，具有巨大的商业化潜力。
