Subject: preliminary PSOMA layout 

I put together two PSOMA layouts, one for a bowtie cavity and one for a ring cavity configuration.

I expect there are a number of problems with the layout as I've drawn it, and I note a number of these in the bowtie diagram. Among these

  • Should I put PSOMA updates in the QIL elog, or in Cryo, SUS, or elsewhere? I think QIL has some 1550nm light, as does cryo. Cryo is pretty crowded, although cryo Q has the possibility of moving to the QIL cryostat.
  • What's the best way to get pump and signal -- signal picked off from the pump, or two separate lasers?
  • I expect this layout is rife with errors in how the locking should go. Shruti and I should probably just talk with someone (and each other) about this rather than listing my various uncertainties.
  • Probably also picked off the homodyne LO from a nonideal place
  • I haven't fully considered a number of things like: mode matching, scattered light, LO phase noise and homodyne angle, etc.
