green setting:
green power (mW) | OPO temperature (kOhm) | p pol PLL (MHz) |
40 | 7.175 | 174 |
IR into filter cavity is around 1 mW. TEM00 is as follows.
AOM frequency (MHz) | IR transmission (cnt) |
109.03683 | 100-130 |
With 40mW green it was difficult to see higher order mode with IR camera. So we decided to increase green power.
