After today's works, 'INCREASING LAS POWER' state stopped working properly.
The laser power does not increase in this state now, and we do not understand the reason at this moment.
I requested PRFPMI RF LOCKED state.
The soon after rotate the HWP PSL, locked loss happened as shown in Fig.1. (During the increase las power)
But, in case of the DOWN state (Just locked the IMC), we can increase the laser power as shown in Fig.2.
And in case of the IRX locked state, when we rotate the HWP, the locked loss happened with the similar situation with Fig..1 (Fig.3.)
So maybe some different would be there around the CARM CMS of input 1
when we rotate the IFO_HWP, the DC PD output of the refl table is decreasing, so IFO HWP worked well.
Also, we performed only the PMC locked and rotate the PSL HWP, the increase of the PSL output increased 0.3 W as expected.
So the HWP would be working well
When I tried to check with IRX again, the behavior was changed, we can increase the laser power without any problem.
When I tried to increase the laser power with PRFPMI RF locked again, the same situation happened again, so we moved to check the UGF of the CARM loop.
