AdV-PSL (Laser Bench setup)

genin, pillant, de rossi, masserot - 21:30 Monday 28 May 2018 (41598)

2 video cameras connected and beam aligned on them.

In order to monitor the drifts of the beam on the laser bench, we have connected and aligned the 2 CMOS video cameras provided by LAPP.

PSL_AMP_Cam is installed on the same beam used by the amplifier diagno box. It monitors the beam after the Laser amplifier.

PSL_PMC_REFL_Cam is installed temporarily on the beam picked-off in transmission of LB_M6 Mirror (slave laser output beam before the Laser amplifier).

The signals PosX and PosY give the centroid positiona and are stored in the data.

NB: the beam going to the PD used to monitor the slave laser output power before the laser amplifier has been sent on the video camera and consequently is not available anymore on the PD.

is there a way to store the centroid position into the data?

if yes can you give the name of the associated signals?

Thanks
