Millimeter-Wave Studies of the 13CH3F Laser. The Effects of Buffer Gases and the Spectroscopy of the Laser States

摘要

Millimeter-wave spectroscopic techniques have been used to study the effects of buffer gases (helium and hexane) on the 13CH3F optically pumped far-infrared laser. The continuous tunability over a wide spectral region and absolute frequency reference of this technique, coupled with the accurately known rotational transition moments, have made possible a number of new measurements and calculations. In this work the diagnostic probe was copropagated with the CO2-laser pump beam through the 13CH3F. The model that we have previously described, which distinguishes among different kinds of rotational transitions, also accounted for these new experimental results also reported in this paper are the results of a spectroscopic study of 13CH3F in its ground and mu (3) = 1 excited vibrational states.
