First demonstration of single-cycle THz pulses at 93 MHz using a resonant cavity and thin lithium niobate, achieving mW-level average power—opening the door to compact, high-efficiency THz sources for imaging and spectroscopy

We demonstrate a record-high THz output of 6.7 mW from large-area photoconductive emitters driven by a frequency-doubled Yb laser at 400 kHz—offering a robust, scalable source for linear and nonlinear THz applications.

We demonstrate the correlation between cumulative hydrodynamics of high-repetition-rate filament plasmas and THz generation efficiency. Our work opens the door for rapid THz-spectroscopy studies with high dynamic range from THz to mid-IR frequencies, significantly accelerating measurement times.
