HBT Alignment & First Measurement

HBT setup was aligned for maximum power on the transmissive arm, then the beamsplitter was tilted to equalize the power in each arm. Then, we set the board at
Total power: 0.156 V
Power on each photodetector: 0.078 V
We left the FROSTI on and will collect data overnight. If we need more power, we can cut the breadboard notch further.
