Research Investigation Directed Toward Extending the Useful Range of the Electromagnetic Spectrum.
Abstract
A method has been developed which provides a complete description of the energy and population distributions in a laser pumped, metastable polyatomic molecule. Different temperatures are required for each mode and for the translational/rotational degrees of freedom. Good agreement between calculated and measured distributions has been found for CH3F. Vibrational energy for this system tends to accumulate preferentially in the nu 3 C-F stretch vibrational mode. As a result, extremely large population inversions are predicted for CH3F when optically pumped by a CO2 laser. These results are expected to apply to many polyatomic molecules.
