Abstract
We report the discovery of four laser emissions from the partially deuterated C-13 methanol isotope 13CD3OH when optically pumped with a cw carbon dioxide (CO2) laser. The wavelengths of these lines, ranging from 45.3 to 108.9 μm, are reported along with their polarizations relative to the CO2 pump laser, operating pressure, and relative intensity. A three-laser heterodyne system was then used to measure the frequencies of eight optically pumped laser emissions from this methanol isotope. These emissions range from 53.4 to 126.1 μm and are reported with fractional uncertainties up to ±2×10-7.
