Abstract
We report 25 new far-infrared laser lines and 26 heterodyne frequency measurements in hydrazine. The frequencies range from 1.0 to 5.5 THz with most of the frequencies between 2.5 and 4.0 THz. The lines were generated in a high frequency, far-infrared Fabry-Perot laser cavity pumped by a CO2 laser. The cavity has a high Q for wavelengths below 150 µm and uses variable coupling to optimize the power for each line.
