The effect of frequency pulling in a He-Ne laser with an inhomogeneously broadened atomic gain line is estimated using the Haken-Sauermann theory. It is shown that the existing asymmetry of the phase characteristic of the atomic gain line profile of a natural mixture of /sup 20/Ne and /sup 22/Ne should lead to a different value of the frequency shift with respect to the line center. The results of experiments, which show satisfactory agreement with the theory, are presented. The maximum frequency shift due to frequency pulling is 135 kHz. It was found that for a symmetrical position of the two lasing frequencies with respect to the line center additional discrimination variations of the phase shift of the frequencies are observed on the discrimination curve. The conclusion is drawn that these variations are due to the effect on the gain profile of burnt-through Lorentz nonlasing holes and lasing holes of the line profile. (AIP)
