Figure 43: Plots of the SQL beating factor (485View Equation) of the detuned interferometer, for different values of the normalized detuning: 0 ≤ β ≡ arctan(δ∕γ ) < π ∕2, and for unified quantum efficiency η = 0.95. Thick solid line: the common envelope of these plots. Dashed lines: the common envelopes (420View Equation) of the SQL beating factors for the virtual rigidity case, without squeezing, r = 0, and with 10 dB squeezing, 2r e = 10 (for comparison).
