[Torrey, Daniel]

We set up a Michelson interferometer with a 14 inch Schnupp Asymmetry to lock the output to midfringe. We added a lens so that the beams are the same size at the beamsplitter and roughly the same Guoy phase. However, modulating the laser's frequency also modulates its power. Next week, we will set up a photodiode with a reference power before the beamsplitter and divide the output with the input to see if the fringe changes.
