We put in the PD in transmission, and here is our lovely signal. We took the beam in transmission and put it through a beamsplitter and then a lens and onto the photodiode and aligned it by moving each beam one at a time and maximizing the DC signal from the PD. We then plugged the AC signal into a spectrum analyzer, and we can see the beat signal at 95MHz.
