The burgeoning field of nonlinear optics is explored in this episode of the Physics World Weekly podcast. It features Nathalie Vermeulen of Brussels Photonics at the Free University of Brussels and Eric Van Stryland of the College of Optics and Photonics at the University of Central Florida. They talk about the science of nonlinear optics and the wide range of applications – from astronomy to quantum computing – that have emerged.

The duo also looks to the future of nonlinear optics and chat about a recent paper in that they have co-authored with 20 other experts in the field. That paper is called “Post-2000 nonlinear optical materials and measurements: Data tables and best practices” and it can be read free of charge in the Journal of Physics: Photonics, where it has been accepted for publication.
