Modeling of PT-systems based on Optical Parametric Amplification and Stimulated Raman Scattering

Most of the research on PT-materials has been performed with the premise that the gain of the system is based on the amplitude-independent or linear amplification mechanisms. In this talk, I will discuss the theoretical model that includes nonlinear optical effects such as Optical Parametric Amplification and Stimulated Raman Scattering to realize larger optical gain. This setup could lead to a build-up of the next generation of PT-materials.
