A compact optical-pump/THz-probe spectrometer based on sub-diffraction field confinement — •Michael Seidel and Georg Herink — Experimental Physics VIII, University of Bayreuth, Germany

Optical-pump/THz-probe spectroscopy presents a powerful scheme for contact-free detection of transient carrier mobilities and relaxation dynamics. In this contribution, we present a novel experimental approach to realize time-resolved time-domain THz spectroscopy (tr-THz-TDS) based on a compact mode-locked fiber laser, efficient frequency conversion and photoconductive detection. Specifically, this approach employs sub-diffraction confinement and optical mode-matching in order to enhance sample excitation and signal strength. The instrument is used to characterize transient carrier dynamics in organic electronic materials and devices.
