I found that green into OPO is completely misaligned. I recovered the alignment by measuring parametric amplification. Here is the information of parametric amplification of BAB.
| green power (mW) | OPO temperature (kOhm) | p pol PLL (MHz) | Vmax (V) | Vmin (V) | parametric gain |
| 0 | 7.2 | 305 | 0.112 | 0.112 | 1 |
| 40 | 7.185 | 165 | 1.82 | 0.04 | 16.3 |
