Towards High-Repetition-Rate Intense Terahertz Source With Metal Wire-Based Plasma

Terahertz radiation can provide unprecedented vistas in physical studies such as transient matter state control and advanced free-electron manipulation. Here, we present one feasible path towards high-repetition-rate, intense THz sources by combining the wire-based THz source on a consecutively running, wire-conveying tape design. The proof-of-principle experimental results show an upper 30 mW average THz power output under 1 kHz laser excitation, which presents the first high-repetition-rate, and most importantly, portable and application in handy THz source that is generated by solid plasmas. The generated THz pulses are characterized with a 0.3 THz center frequency and similar to 0.3 THz bandwidth. We believe this tabletop laser-driven high-repetition-rate THz source will open a new door for THz and related interdisciplinary sciences.
