We found optimal temperature region which doesn't have mode hopping for three lasers and has beat note with 7 MHz for ML-CC PLL and below 400 MHz for ML-p pol PLL and overlapping of CC and p pol inside OPO.

P pol beat note when CC and p pol is overlapping inside OPO is 69.8 MHz without green.

With green power of 68 mW, p pol overlapping beat note is around 7 MHz. The laser setting is as follows.

We have to lock p pol at p pol beat frequency +- 7 MHz, so p pol beat note around 7 MHz is not good. To change the p pol beat frequency, we changed OPO temperature from 7.05 kOhm to 7.02 kOhm. The p pol beat frequency became 56 MHz.
