Recently we couldn't lock FC and we thought it is due to strong wind, but today we found that green injection power was 11.5 mW which was a bit lower than usual. When we increased FC gain, FC locked. Then we changed SHG temperature from 3.078 to 3.09 and green injection power became 15.2 mW. We tuned the FC gain so that UGF of FC loop is 20kHz.
