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…

Sample thickness measurements by phase-sensitive terahertz upconversion detection
Tobias Pfeiffer, Jens Klier, Georg von Freymann +1
Nonlinear frequency conversion provides an elegant method to detect photons in a spectral range which differs from the pump wavelength, making it highly attractive for photons with…
