Abstract
Energy transfer and collisional processes have been studied in the $^{13}CH_{3}F$ optically pumped far-infrared laser by means of millimeter wave spectroscopy. Synchronous chopping of the infrared pump beam and fast digital data collection allow the calculation of absolute absorption/emission coefficients. The observation of hole burning phenomena makes possible a study of the transition from inhomogeneous to homogeneous broadening. These processes in the rotational levels of both the ground and excited vibrational states have been modeled. This computer simulation is the connection between the experimental data and the detailed internal mechanism of the laser. Measurement of the unpumped absorption transition frequency provides an unbiased laser frequency.
