    * Suppress angular modes by XX
    * Suppress laser noise at the 11 & 55 MHz readout frequencies by XX
    * Suppress angular modes by XX (note that the IMC also filters the beam jitter)
    * Suppress laser noise at the 11 & 55 MHz readout frequencies by XX (this is primarily a PMC function as the IMC transmits the sidebands)

Power calculation

P_arm = Plaser * T_PMC * T_IMC * T_FI * alpha_MM * G_PR * T_BS * G_arm

(Gautam put some numbers here for the terms please)

  1. What should our PMC Finesse be so that its barely enough to satisfy filtering reqs and transmission efficiency?
    • Suppress angular modes by XX (note that the IMC also filters the beam jitter)
    • Suppress laser noise at the 11 & 55 MHz readout frequencies by XX (this is primarily a PMC function as the IMC transmits the sidebands)

    • Maintain a T_PMC > 0.9X

  2. What's up with our T_IMC ?
    • let's clean the IMC mirrors
    • what's the MM frac between PMC and IMC?
  3. Is our T_FI too low?
    • measure this during the vent when we clean the IMC
  4. What is the loss in the PRC?
    • clipping in the PRC
    • new PR/SR mirrors
