The brightness of a light source defines its applicability to nonlinear phenomena in science. Bright low frequency terahertz (< 5THz) radiation confined to a diffraction-limited spot size is a present hurdle due to the broad bandwidth and long wavelengths associated with single-cycle terahertz pulses as well as due to the lack of terahertz wavefront correctors. Here, using a present-technology system, we employ a new concept of terahertz wavefront manipulation and focusing optimization. We…

A magnetic non-reciprocal isolator for broadband terahertz operation

This work demonstrates a non-reciprocal terahertz Faraday isolator, operating on a bandwidth exceeding one decade of frequency, a necessary requirement to achieve isolation with the (few-cycle) pulses generated by broadband sources.

Observation of gigawatt-class THz pulses from a compact laser-driven particle accelerator.

Subpicosecond terahertz pulses with energies ≥460 μJ from a laser-driven ion accelerator are observed, thus rendering the peak power of the source higher even than that of state-of-the-art synchrotrons.
