“…Efficient output couplers must have the following properties : optimum IR reflection coefficient to operate with a collimated pump beam, low FIR absorption losses and low adjustable coupling coefficient (5-10 %). Hybrid couplers meeting this requirements have been realized at wavelengths larger than 100 pm [ 19,20,21 ] . At wavelengths smaller than 100 ktm technological problems arise from the FIR absorption of the IR reflecting coating and the increasing difficulty to match the etalon conditions of the hybrid coupler substrate, thus we have used the conventional output hole mirror in the present experiments.…”

2014 On décrit la réalisation et les performances d'un laser continu à alcool de structure guide d'onde pompé optiquement. Il assure un fonctionnement stable dans le domaine des courtes longueurs d'onde submillimétriques avec un niveau de puissance de 10 à 100 mW. Des résultats significatifs présentés à 70 03BCm et 118 03BCm soulignent les lignes directrices essentielles au choix des paramètres du laser.Abstract. 2014 The design and performances of an efficient CW waveguide optically pumped CH3OH laser are described for stable operation 10-100 mW level in the short submillimeter wavelength region. Significant results at 70 03BCm and 118 03BCm underline the more stringent guide-lines in the selection of the laser parameters.

“…2-4 Metal meshes have been used as mirrors for improving the pumping efficiency in optically pumped infrared ͑IR͒ lasers. 5,6 FSSs have also been used in the farinfrared region as beam splitters, 7,8 filters, 9,10 polarizers, 11,12 output couplers for lasers, 13 and Fabry-Perot interferometers. 14,15 Continuing advancements in lithography have allowed the element dimensions to be scaled down, thus obtaining FSSs with response in the IR portion of the spectrum.…”

“…This mirror should have high reflectivity at the pump wavelength, Xp, and partial reflectivity and low absorptivity at the FIR wavelength, XFIR, and should couple out over a broad area of the laser mode to limit diffraction. Among the schemes that have been used to meet these requirements are hybrid metal-mesh dielectric (MMD) mirrors, 4 ' 5 hybrid metal dielectric hole (MDH) couplers, 1 ' 2 etalons," 5 ' 6 and capacitive-mesh couplers. 7 This Letter reports on the extension of the use of capacitive-mesh couplers throughout the FIR spectrum and the use of a novel hybrid capacitive-mesh hole coupler for improved performance at shorter FIR wavelengths.…”
