By reducing green pump power from 26.7mW to 18mW, we managed to reproduce the last Friday's FDS measurement. The detuning is around 100-130Hz. It seems that squeezing level at low frequency is still limited by locking accuracy.

The parameters are as follows.

sqz_dB = 7;                    % produced SQZ

L_rt = 150e-6;                    % FC losses

L_inj = 0.20;                     % Injection losses

L_ro = 0.11;                      % Readout losses

A0 = 0.05;                         % Squeezed field/filter cavity mode mismatch losses

C0 = 0.05;                         % Squeezed field/local oscillator mode mismatch losses

ERR_L =   13.3e-12;                  % Lock accuracy [m]

ERR_csi = 80e-3;                  % Phase noise [rad]
