Compact, robust and broadband sources in the terahertz range are extremely important in diverse applications such as spectroscopy, imaging, communication, and radar. A review of the current state-of-the-art is presented with emphasis on Schottky diode based frequency multiplier technology. Frequency multiplier circuit chips fabricated on few micrometer thick GaAs membranes and packaged in low-loss waveguide circuits have demonstrated tens of microwatts of output power up to 1.9 THz. This breakthrough has enabled sensitive heterodyne receivers in the terahertz range that will be flown on an upcoming ESA mission to answer fundamental questions about our universe.

2014 Une analyse quantitative du rendement en puissance du laser CH3OH à 118 03BCm est présentée. Un modèle à taux de population a été étendu dans ce but à cette transition à courte longueur d'onde dont l'élargissement est Doppler ou mixte. Des expériences de diagnostics sur cette raie laser permettent la mesure de certains des termes qui déterminent le rendement du laser, ainsi que l'analyse de la puissance de sortie. Elles montrent aussi le degré appréciable de saturation lointain infrarouge pour un large domaine des valeurs des paramètres.

“…Consequently a good amplitude stability of the FIR is obtained with a good frequency stabilization of the CO2. The stabilization system which is used is quite simple and has been described earlier [22]. The CO2 laser is frequency locked by maximizing the FIR amplitude, i.e., the power level of the FIR beam coupled out at the input mirror in our case (see Fig.…”

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.
