Lithium niobate (LN), first synthesized 70 years ago, has been widely used in diverse
applications ranging from communications to quantum optics. These high-volume …

Optical rectification of femtosecond laser pulses has emerged as the dominant technique for
generating single-and few-cycle terahertz (THz) pulses. The advent of the tilted pulse front …

Extremely strong‐field terahertz (THz) radiation in free space has compelling applications in
nonequilibrium condensed matter state regulation, all‐optical THz electron acceleration and …

In this work, we improve the performance of an optically pumped spintronic terahertz emitter
(STE) by a factor of up to 6 in field amplitude through an optimized photonic and thermal …

Particles at relativistic energies form the basis of acceleration science. The emergence of
terahertz-driven acceleration promises vastly smaller and cost-efficient accelerators; …

Recently, ferromagnetic‐heterostructure spintronic terahertz (THz) emitters have been
recognized as one of the most promising candidates for next‐generation THz sources …

Bridging the “terahertz gap “relies upon synthesizing arbitrary waveforms in the terahertz
domain enabling applications that require both narrow band sources for sensing and few …

Using a 400 μJ ytterbium laser combined with a novel pulse compression technique, we
demonstrate a state-of-the-art terahertz (THz) source from the tilted-pulse front pumping …

Spintronic heterostructures consisting of ferromagnetic (FM) and nonmagnetic (NM) have
become increasingly important devices for terahertz (THz) pulse generation, named as …

Terahertz-driven acceleration has recently emerged as a route for delivering ultrashort bright
electron beams efficiently, reliably and in a compact set-up. Many working schemes and key …
