Long-lived, pulse-induced absorption in ${\mathrm{LiNb}}_{1-x}{\mathrm{Ta}}_x{\mathrm{O}}_3$ 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 ${\mathrm{LiNb}}_{1-x}{\mathrm{Ta}}_x{\mathrm{O}}_3$ (LNT) solid solutions with the goal to probe the in…
