Abstract :
Summary form only given. THz sources based on cascaded frequency multipliers are described. These operate at room temperature, have excellent signal quality and are frequency tunable. A 1.9 THz source generates greater than 10uW. More recently sources at 2.5 and 2.7 THz have generated 2uW. These power levels are useful as local oscillators for astronomical receivers, such as those on the SOFIA airborne observatory.
