Terahertz local oscillator for the Microwave Limb Sounder on the Aura satellite

The Microwave Limb Sounder on the Aura satellite has a radiometer at 2.5 THz to perform global mapping of OH in the atmosphere. The OH radiometer utilizes two Schottky-diode mixers pumped by an optically pumped THz gas laser local oscillator. The laser was first turned on in space on July 22, 2004, and has performed without issue for more than 30 months. The specifications, design, and modeling of this 2.5 THz laser local oscillator are presented here, along with some of the important design validation and test results.

Large-volume pulsed-RF excited waveguide CO/sub 2/ lasers

Robert T. Brown; Leon A. Newman; Michael W. Murray; Richard A. Hart

Scalable pulsed-RF excitation of a sealed-off non-flowing CO/sub 2/ laser in a configuration compatible with high transverse and high longitudinal mode purity and compatible with very compact laser designs is described. The variation of maximum pulse-repetition frequency (PRF) with discharge transverse dimensions and the effects of electric field uniformity are described. Kinetics code calculations and laser design studies indicate that the results are scalable to the 10-J, 50-Hz level. >
