Self-selected phase-matched second harmonic generation in nonlinear optical materials: from phenomenon to applications
Niklas Dömer, Tobias Hehemann, Felix Sauerwein +3
Self-selected phase-matched second harmonic generation is introduced as an all-optical probe of refractive-index dispersion in birefringent nonlinear optical materials. Rather than…
Ground- and excited-state properties of LiNbTaO solid solutions
Felix Bernhardt, Florian A. Pfeiffer, Felix Schug +5
LiNbTaO solid solutions are investigated from first principles and by optical spectroscopy. The ground- and excited-state properties of the solid solutions are mode…
Long-lived, pulse-induced absorption in solid solutions: the case of three intrinsic defect sites for electron localization with strong coupling
Niklas Dömer, Julian Koelmann, Mira Hesselink +6
Femto-/nanosecond pulse-induced, red and near-infrared absorption is studied in (LNT) solid solutions with the goal to probe the in…
Small electron polarons bound to interstitial tantalum defects in lithium tantalate
Anton Pfannstiel, Tobias Hehemann, Nils A. Schäfer +8
The absorption features of optically generated, short-lived small bound electron polarons are inspected in congruent lithium tantalate, (LT), in order to address th…
