摘要:

报道了在高重复频率、低脉冲能量激光系统中相干产生和探测带宽为0.1-9 THz的太赫兹脉冲。在这项工作中,我们展示了固态偏置相干检测结合自旋电子发射器的应用和评估。这种组合用于在时域光谱(TDS)装置中产生和检测太赫兹脉冲,并在体非线性晶体上进行测试。这些结果建立了一个新的有前途的候选人,以扩大由高重复率激光驱动的紧凑,宽带THz TDS系统的可能性。

英文摘要:

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.
