   Thanks for the response!   
      
   I have confirmed via measurements that in my source power regime of interest,   
   the sensor noise is limited by RIN (though in other regimes etalon fringes are   
   more important). A reduction in RIN by 30-40 dB would be more than   
   satisfactory!   
      
   Would I need to make significant modifications to the "without tears" laser   
   noise canceler circuit to   
      
   1. Add the signal and comparison photocurrents while still locking the DC   
   values to be the same, and   
   2. Have enough bandwidth to transmit the sensor signal at f~100-600 kHz?
