Far-infrared superradiance in methyl fluoride
… laser operated on the P(20) line at 9.55 ~m. The far-infrared (FIR) super-radiant pulses, at a wavelength of 496 microns, were identified by the pressure (p) dependence of their widths and delays (inversely proportional to p) and their intensities (as p2). These pulses were observed by a fast, …

Far infrared absorption in superconducting niobium alloys
… Nb - Mo have been measured by the absorption of far-infrared radiation. The gap edges are sharp and there is no notable structure on the curves. No ,attempt was made to compare the shapes of the curves with theory, since certain parameters required for the theoretical calculation were not known. …

GaAs/AlGaAs far-infrared quantum cascade laser
… feasibility of an optically pumped inter subband farinfrared (40-100[mu]m) laser, using GaAs/ AlxGal-xAs heterostructures. The proposed design aims to use LO-phonon-mediated depopulation of the lower THz laser level to aid the intersubband laser population inversion. Interband recombination occurs …

Analysis of Quasi-Optical Components for Far-Infrared Astronomy
This thesis is concerned with the development and analysis of quasi-optical components used in experiments to measure of the CMB in the terahertz and submillimetre wavebands. I have concentrated on corrugated horn structures in the Planck and QUBIC experiments. A precise analysis of the …

The far-infrared absorption spectrum of low temperature hydrogen gas
The far-infrared absorption spectrum of normal hydrogen gas has been measured from 20-320 cm' (A=500-31 pm), over the temperature range 21-38 K, and the pressure range0.6-3 atmospheres. The spectra cover the very weak and broad collision-induced translational absorption band of 112 which at these …
