TL;DR: In this paper, the authors present wide-band spectral measurements of coherent transition radiation which they use for temporal characterization and show that the electron beam, produced using controlled optical injection, contains a temporal feature that can be identified as a 15 pC, 1.4-1.8 fs electron bunch (root mean square) leading to a peak current of 3-4 kA depending on the bunch shape.
Journal ArticleDOI
Electro-optic detection of terahertz radiation
TL;DR: In this article, a complete frequency-domain description of electro-optic (EO) detection of terahertz (THz) electromagnetic radiation, including a description of the ellipsometry technique employed, is presented.
Journal ArticleDOI
Femtosecond dynamics of hydrogen bonds in liquid water : a real time study
TL;DR: In this article, a pump-probe experiment is described to study femtosecond dynamics of hydrogen bonds in liquid water, where the key element of the experimental setup is a laser source emitting 150 fs pulses in the 2.5-4.4 mm spectral region, at a 10 mJ power level.
Journal ArticleDOI
Terahertz achromatic quarter-wave plate
TL;DR: This achromatic wave plate demonstrates a huge frequency bandwidth (upsilonmax/upsilonmin approximately 7), and therefore can be applied to terahertz time domain spectroscopy and polarimetry.
Journal ArticleDOI
Measurements of the thz absorption and dispersion of znte and their relevance to the electro-optic detection of thz radiation
TL;DR: In this article, the authors measured the absorption and index of refraction of single-crystal ZnTe from 0.3 to 4.5 THz and found that the absorption is dominated by two lower-frequency phonon lines at 1.6 and 3.7 THz.
