[Torrey, Daniel]

We aligned the beam through a f = 150 mm lens, into the AA AOM, through an iris, through a quarter waveplate, and reflected back using a concave mirror (R = 100 mm). This use of the curved mirror intended to allow us to adjust the AOM frequency without needing to realign the beam into the fiber. We currently see 3 beams from the AOM after the PBS. We aren't sure which beam is which. In theory, the twice shifted beam will not move when we change the AOM frequency. In practice, this might not be the case. We will work on this next week.
