Several scientific and industrial applications, such as spectroscopy [1], imaging [2], medicine [3], biology [4], material science [5] and security [6], now depend on terahertz radiation as a key instrument. The development of the overall magnetism domain and more specifically the physics of electron spin over the past 25 years have opened the doors to explore new potential and promising THz...
Terahertz (THz) radiation finds extensive applications in a wide range of fields [1-4]. Recently, there has been a growing interest in high repetition rate, high peak power THz radiation sources due to their ability to observe temporary phenomena in materials [1], enable real-time THz spectroscopic imaging of molecules [2], and serve as sources for electronic/ion emission (Scanning Tunneling...
Spintronic terahertz emitters have attracted considerable interest within the last decade. They promise terahertz sources with unmatched broad frequency bandwidth which are easy to manufacture and operate, and therefore easy to scale at low cost.
However, the experiments and proofs of concept rely on free-space ultrashort-pulsed pump lasers and rather complex benchtop setups.
This...
Terahertz (THz) radiation emission from laser plasma, achieved by focusing two-color femtosecond pulses in air or gas, is widely utilized for its broad spectrum and relatively high peak intensity. Optimizing the THz yield from two-colour plasma is crucial to approach the signal levels attained in crystals. The pulse chirp plays a significant role in controlling the THz-optical conversion...
