We report the coherent generation and detection of terahertz (THz) pulses with a spectral bandwidth of 0.1-9 THz using a high repetition rate laser system. By combining a solid-state biased coherent detector with a spintronic emitter, we successfully measured the ultra-broadband THz frequency optical properties of bulk crystalline materials using time-domain spectroscopy.
We report the coherent generation and detection of terahertz (THz) pulses featuring a spectral bandwidth in the range of 0.1-9 THz achieved via the use of a high repetition rate (250 kHz), low pulse energy (6.2 mu J) laser system. More specifically, we test and evaluate a solid-state biased coherent detection device in combination with a spintronic emitter. We demonstrate the use of this combination of techniques to measure the ultra-broadband THz frequency optical properties of bulk crystalline materials with time-domain spectroscopy.(c) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
