Ultrafast Electron Temperature Dynamics in Spintronic Terahertz Emitters Studied by Optical-Pump Terahertz-Probe Spectroscopy

Felix Selz, Johanna Kölbel, Felix Paries +3

Spintronic terahertz emitters (STEs) pumped by femtosecond lasers have become a widely used source of broadband terahertz radiation. However, the strength of the emitted field is l…

Influence of an external electric field on the energy dissipation at the initial stage of laser ablation

S. Hirtle, P. N. Terekhin, M. Schäfer +4

A density-dependent two-temperature model is applied to describe laser excitation and the following relaxation processes of silicon in an external electric field. Two approaches on…

In-Plane Focusing of Terahertz Surface Waves on a Gradient Index Metamaterial Film

Martin F. Volk, Benjamin Reinhard, Jens Neu +2

We designed and implemented a gradient index metasurface for the in-plane focusing of confined terahertz surface waves. We measured the spatial propagation of the surface waves by…
