,One Artist’s Neurosis on Signing,. In previous experiments values of the quality factor as high as 3 × 10. have been achieved for the resonant mode, corresponding to an average lifetime of a photon in the cavity of 0.2 s. The photon lifetime is thus much longer than the interaction time of an atom with the maser field. The atoms us
