We present a frequency modulation scheme to detect atoms dispersively in a high-finesse optical cavity at low-light levels with immunity to cavity length fluctuations. We use multiple cavity resonances to provide common mode noise rejection, keeping the high intensity carrier off-resonant from all cavity modes. The method has applications in atomic squeezed state generation and quantum metrology.

  9. Cavity FSR and microwave fluctuations have each been measured at <10Hz rms, whereas atomic shot noise for 105 atoms and Δ=1GHz, is ∼600Hz rms.
  10. Since the difference in rf frequencies is likely to be in the audiofrequency range, this essentially eliminates rf noise from the equation.
