de Lange G, Krieg J-M, Honingh N, Karpov A, Cherednichenko S. Performance of the HIFI flight mixers. In: Proc. 19^th Int. Symp. Space Terahertz Technol.; 2008. p. 98–105. Abstract: We summarize the technology and final results of the superconducting heterodyne SIS and HEB mixers that are developed for the HIFI instrument. Within HIFI 7 frequency bands cover the frequency range from 480 GHz to 1910 GHz. We describe the different device technologies and optical coupling schemes that are used to cover the frequency bands. The efforts of the different mixer teams that participate in HIFI have contributed to an instrument that will have unprecedented sensitivity and frequency coverage. Keywords: HEB mixer applications, HEB applications https://db.rplab.ru/refbase/show.php?record=1074
Angeluts AA, Bezotosnyi VV, Cheshev EA, Goltsman GN, Finkel MI, Seliverstov SV, et al. Compact 1.64 THz source based on a dual-wavelength diode end-pumped Nd:YLF laser with a nearly semiconfocal cavity. Laser Phys. Lett.. 2014;11(1):015004 (1 to 4). Abstract: We describe a compact dual-wavelength (1.047 and 1.053 μm) diode end-pumped Q-switched Nd:YLE laser source which has a number of applications in demand. In order to achieve its dual-wavelength operation it is suggested for the first time to use essentially nonmonotonous dependences of the threshold pump powers at these wavelengths on the cavity length in the region of the cavity semiconfocal configuration under a radius of the pump beam smaller than the radius of the zero Gaussian mode. Here we demonstrate one of the most interesting applications for this laser: difference frequency generation in a GaSe crystal at a frequency of 1.64 THz. A superconducting hot-electron bolometer is used to detect the THz power generated and to measure its pulse characteristics. Keywords: HEB applications, HEB detector applications, short THz pulses detection https://db.rplab.ru/refbase/show.php?record=1076
