THz time-domain spectroscopy of high Tc substrates
(AIP Publishing, 1990-09-03)
Using the method of time-domain spectroscopy, we have measured the absorption and dispersion from 0.2 to 2 THz of the high Tc substrates, magnesium oxide, yttria-stabilized zirconia (YSZ), and lanthanum aluminate. Our ...
Far-infrared time-domain spectroscopy with terahertz beams of dielectrics and semiconductors
(Optical Society of America, 1990-10)
Using the method of time-domain spectroscopy, we measure the far-infrared absorption and dispersion from 0.2 to 2 THz of the crystalline dielectrics sapphire and quartz, fused silica, and the semiconductors silicon, gallium, ...
THz commensurate echoes: Periodic rephasing of molecular transitions in free-induction decay
(American Physical Society, 1991-04-08)
We report the first study of coherent transients excited by ultrafast pulses of THz radiation. Using a newly developed optoelectronic source of well-collimated beams of subpicosecond pulses of THz radiation to excite N2O ...
