Mayank, Siva and I worked on alignment yesterday to ensure that the internal alignment is still set. The alignment to the QPD should be the same alignment to the PDs, for instance. With the addition of the iris as an alignment reference we wanted to ensure that this reference still head.

We were able to maximize the QPD and PDs powers simultaneously with the iris installed, confirming everything is internally aligned. However, we are clipping on the iris aperature and need a smaller beamsize through the iris to remove this. Without the iris, our common maximized alignment yielding a QPD power of about .9 mW, while with the iris installed we have about .76 mW.
