摘要：

Low-background sub-Doppler saturated absorption line shapes were obtained for SF6 with a CO2 laser. With the use of a high-power pump, linewidths near the collisional relaxation width have been observed. The theory for a two-level model has been calculated and shows that the rate-equation approximation overestimates the line narrowing because of the propagation effect. Consistent with experiments, for linear absorption coefficients alpha-l of less than 15, no subnatural line is predicted.
