Solid-State Biased Coherent Detection of Ultra-Broadband Terahertz Pulses for high repetition rate, low pulse energy lasers (2201.12627v1)
Published 29 Jan 2022 in physics.optics and physics.app-ph
Abstract: We report the coherent generation and detection of terahertz (THz) pulses covering the bandwidth of 0.1-9 THz in a high repetition rate, low pulse energy laser system. In this work we demonstrate the application and evaluation of solid-state biased coherent detection in combination with a spintronic emitter. This combination was used to generate and detect THz pulses in a time-domain spectroscopy (TDS) setup and tested on bulk nonlinear crystals. These results establish a new promising candidate to extend the possibilities for compact, broadband THz TDS systems driven by high repetition rate lasers.
