Principles of Terahertz Science and Technology
TL;DR: The principles of terahertz science and technology as discussed by the authors aims to elucidate the fundamentals of THz technology and science for potential new users, and also discusses a number of essential processes where THz waves interact with physical, chemical and biological systems.
Journal ArticleDOI
Time-resolved electron-temperature measurement in a highly excited gold target using femtosecond thermionic emission.
TL;DR: Direct measurement of hot-electron temperatures and relaxation dynamics for peak electron temperatures between 3400 and 11000 K utilizing two-pulse-correlation femtosecond thermionic emission is reported.
Journal ArticleDOI
Generation of narrow-band terahertz radiation via optical rectification of femtosecond pulses in periodically poled lithium niobate
Yun-Shik Lee,T. Meade,V.E. Perlin,Herbert G. Winful,Theodore B. Norris,Almantas Galvanauskas +5 more
TL;DR: In this article, femtosecond optical pulses are propagated through a periodically poled lithium-niobate crystal, where the domain length is matched to the walk-off length between the optical and THz pulses.
Journal ArticleDOI
Multiphoton absorption and nonlinear refraction of GaAs in the mid-infrared
TL;DR: In this article, the wavelength dependencies of the two-and three-photon absorption coefficients of undoped GaAs in the spectral range 1.3-3.5 microm were reported.
Journal ArticleDOI
Exciton dynamics in atomically thin MoS2: Interexcitonic interaction and broadening kinetics
TL;DR: In this paper, the authors investigated the interaction dynamics of two important direct-gap excitons and their associated broadening kinetics in ultrafast pump-probe spectroscopy.
