Measurement of Laser Frequencies from CD3OH and CD3OD up to 8.6 THz
Department or Administrative Unit
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.
