The CO/sub 2/-pumped CF/sub 4/ laser is a potentially useful source of line-tunable infrared radiation in the region 605 to 655 cm/sup -1/, and the spectroscopy of CF/sub 4/ has been carried to the point that the laser frequencies that will result from any given pump line can be calculated to better than 0.01 cm/sup -1/. We now report quantitative intensity and line-broadening studies on CF/sub 4/ and their application to modeling the laser gain. First, absorption measurements on isolated lines in the ..nu../sub 2/ + ..nu../sub 4/ pump band at a series of pressures yield an effective transition dipole moment for this band of 0.010 Debye. At the same time the transition moment for the (..nu../sub 2/ + ..nu../sub 4/) - ..nu../sub 2/ laser band has been calculated and agrees well with the results of laser self-absorption measurements. Finally, linewidths determined as a function of pressure yield a pressure-broadening coefficient of ca. 10 MHz/torr, significantly greater than that expected from a hard-sphere gas-kinetic model. From these data the gain of the CF/sub 4/ laser can be calculated at various pressures and temperatures; the results are in reasonable agreement with measured values.
