Abstract :
The first laser action produced by the partially deuterated isotopic form of methanol, 13CHD2OH, has been observed. With this laser medium, eight far-infrared laser emissions were discovered having wavelengths ranging from 33.8 to 80.9 mum. A three-laser heterodyne system was used to measure the frequencies for these newly discovered laser lines and are reported with fractional uncertainties of plusmn3 times 10-7. The offset frequency of the CO2 pump laser was measured with respect to its center frequency for each 13CHD2OH laser emission.
