Figure 43: Plots of the SQL beating factor (485) of the detuned interferometer, for different
values of the normalized detuning: , and for unified quantum efficiency
. Thick solid line: the common envelope of these plots. Dashed lines: the common
envelopes (420) of the SQL beating factors for the virtual rigidity case, without squeezing, ,
and with 10 dB squeezing, (for comparison).
