TLDR
In this article, it was shown that the dependence of the output of a whisker diode on its orientation in the polarized beam of an infrared laser can be explained on the basis of simple long-wire antenna theory.Abstract:
It is shown that the dependence of the output of a whisker diode on its orientation in the polarized beam of an infrared laser can be explained on the basis of simple long‐wire antenna theory. Outstanding improvements in coupling the diode to the radiation field can result when this fact is utilized in applications.read more

Terahertz Near-Field Nanoscopy of Mobile Carriers in Single Semiconductor Nanodevices
TL;DR: It is found that the mobile carrier contrast can be directly related to near-field excitation of THz-plasmons in the doped semiconductor regions, which opens the door to quantitative studies of local carrier concentration and mobility at the nanometer scale.

Enhanced dielectric contrast in scattering-type scanning near-field optical microscopy
Bernhard Knoll,Fritz Keilmann +1 more
TL;DR: In this paper, the authors show that the coupling of probe dipole and its image in the sample causes a steep increase of scattering cross-sections at small probe-sample distances.

Accurate frequencies of molecular transitions used in laser stabilization: the 3.39‐μm transition in CH4 and the 9.33‐ and 10.18‐μm transitions in CO2
TL;DR: In this paper, the frequencies of three lasers stabilized to molecular absorptions were measured with an infrared-frequency synthesis chain extending upwards from the cesium frequency standard, and the measured values are 29.442 483 315 (25) THz for the 10.18μm R(30) transition in CO2, 32.134 266 891 (24) THZ for the 9.33μm RCR(10) transition, and 88.376 181 627 (50) THtz for the 3.39μm P(7)-transition

ABSOLUTE FREQUENCY MEASUREMENTS OF THE 28‐ AND 78‐μm cw WATER VAPOR LASER LINES
TL;DR: The two highest frequency measurements as yet reported are described in this paper, where the 28 and 78μm cw water vapor laser lines were found to be 10.718073±0.000002 THz and 3.821775± 0.000003 THz, respectively, by beating each of these radiations with the 337 and 373μm (0.89 and 0.80 THz) radiation from an HCN laser, in a metal-on-metal point-contact diode.
