The Nonlinear Optics group, based at the University of St Andrews School of Physics & Astronomy, focuses on research and development of nonlinear optical devices. Our group, in its previous incarnation as the CW-OPO group, has many years of experience developing devices that leverage the fundamental properties of nonlinear materials to frequency-convert coherent sources of radiation. Most recently, we have used these techniques to develop a compact source of Terahertz (THz) radiation. Since the main focus of our research is now THz parametric generation and applications development within this area, the title "CW-OPO" group is no longer appropriate (especially since we currently have only one CW-OPO programme running).
Our new research direction capitalises on many techniques developed by the group over the past few years. In particular, work on intracavity optical parametric oscillation has been adapted to help develop a compact THz source. Other research activities that will feed into this, include the development of novel quasi-phasematching geometries for parametric generation. This new website will grow over the coming months as we adapt material from our previous site and update pages with new content.
