 note = {A theory for a gas laser with a Gaussian radial field distribution is considered. Rotating wave approximation is adopted to calculate the atomic polarization of the two−level system. An asymmetry of the shape of the Lamb dip and a shift of its center frequency are numerically obtained in the self−consistent laser field.},
