* PRFPMI with AS17 + OMC DC readout done * 1.2 W output from IMC (7 W when O3GK) * Roll off the MICH and PRCL control * Same feed forward for MICH and PRCL from O3GK * Sensitivity [[https://dac.icrr.u-tokyo.ac.jp/KAGRA/DAWG/Detchar/klog/klog23945|url]] * Future work * Evaluate the noise budget * Sensing noise [MICH/PRCL/CARM] * Angular noise [Suspension] * Environmental noise * etc * Check the scattering light * Improve the suspension control * Alignment sensing and control * Interferometer characterization * Increased the laser power
