Current situation of IR alignment

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.
