Abstract

Twenty two laser frequencies, whose values range from 1.6 to 8.6 THz, have been measured for the first time using heterodyne techniques. These laser emissions were generated by an optically pumped molecular laser that used either CD₃OH or CD₃OD as its lasing medium. At least three of the observed laser emissions generated by CD₃OH were discovered during this investigation and the first laser frequencies measured for CD₃OH above 8 THz are reported. The laser frequencies were measured with fractional uncertainties up to ± 2 × 10⁻⁷, of sufficient accuracy to confirm two proposed far-infrared laser assignments. The offset frequency of the CO₂ pump laser with respect to its center frequency was also measured for nearly all laser emissions generated by CD₃OH.
