Small, strong-coupling polarons
Lithiumniobate, LiNbO3, is one of the most important materials in linear and nonlinear photonics. It is a promising material not only in many applicative fields like real-time, 3D holographic displays or THz photocunductive switching, but also as a reference material in the field of nonlinear optics. At high light intensities small polarons are formed, which are due to their strong absorption and their dynamic in the sub-ps-timescale, a promising quasiparticle for the ultrafast control of light with light. In this project we observe polaron behavior in the visible, near- and mid-infrared spectral range, using a combination of experimental methods in the ultrafast-physics and -spectroscopy with dynamic holographic measurements.
