    "abstract": "We show that an intra-cavity medium with normal dispersion reduces the\nsensitivity of the cavity resonance frequency to a change in its length by a\nfactor inversely proportional to the group index. Since the group index in an\natomic medium can be very large, this effect can help in constructing highly\nfrequency-stable cavities for various potential applications without taking\nadditional measures for mechanical stability. The results also establish\nindirectly the opposite effect of enhanced sensitivity that can be realized for\na negative dispersion corresponding to a group index close to a null value.\nThis enhancement in turn can be employed to increase significantly the\nsensitivity of a ring laser gyroscope.",
