We had the laser aom and QPD in line with nothing between the components. Pranav then adjusted the AOM so that the laser would pass through the AOM crystal at different points.

Note: The square on the top is supposed to represent the AOM crystal and there is supposed to be a circle inside it indicating the position of the laser beam, but it only worked in image 5.

  • closest to transducer

  • middle of crystal

  • away from transducer but near middle

    away from transducer but near middle

  • farthest from transducer slightly clipped

    farthest from transducer slightly clipped

So it seems that the closer to the transducer the less oscillation there is and also the less drift there is.
