Highly-Stable Laser-Driven Single-Cycle Intense Terahertz Source with 100 kHz Repetition Rate

Over the last decade, significant advances have been made in the implementation of high-performance benchtop pulsed THz sources featuring optical rectification of ultrashort light pulses in nonlinear crystals [1]. On the one hand, the use of lithium niobate (LN) crystals, with a tilted pulse front pumping (TPFP) configuration, has enabled the emergence of intense THz sources [2]. On the other hand, the development of diode-pumped ytterbium-doped lasers with high repetition rates has led to the advent of powerful THz sources [3]. These developments are timely because THz sources combining such performances, namely high intensity and high repetition rate, are essential for many applications such as matter analysis and manipulation [4].
