I switched the NEOLASE laser to the original FB laser, and PMC and IMC were locked smoothly

Then PLLX and PLLY were locked with some temperature shift from 30.7 to 23.5 degree for PLLX, and 27.8 to 21.9 degree for PLLY.

PMC UGF has been set to around 5kHz, the measured visibility is about 95%, and the transmitted power is about 17W.

IMC UGF has been set to 100kHz, and the crossover frequency has been set to 14kHz. They have the similar values as klog:26661.  These measurements were done with 4.7W output power at IMC.
