The green fiber power drop posted in 45903 happened 7 days after the chamber was pumped down (VacGnPwr.pdf attached). This low resolution spot also shows a large spike in the green power fluctuations. This was before we managed to stabilize the green power (by tweaking the laser mode, polarization through the EOM and adding a noise eater).

GnSpike.pdf (attached) shows a higher resolution plot of this power spike to confirm the maximum height and duration. After this power spike we are still able to achieve ~50% throughput from launch power to refl diode although it is sporadic and quite unstable.
